[Bug 9056] Mono 1.2.4 fails to find mscorlib.dll on startup
by wine-bugs＠winehq.org 15 Sep '07

http://bugs.winehq.org/show_bug.cgi?id=9056 --- Comment #14 from Anastasius Focht <focht(a)gmx.net> 2007-09-15 15:53:38 --- Hello again, well actually there are more bugs in mono and wine regarding the assembly loading mechanism. Start your engines ... used: mono 1.2.5 win32 wine-0.9.44-379-g82ef8d7 After using the AOT cache and msvcrt._wspawnvp() workaround i stumbled over .NET gui app (windows forms) which uses pinvoke() calls to user32.dll. The loader tries to locate the user32.dll and crashes. --- snip --- ... fixme:msvcrt:_wspawnvp stub Mono-INFO: Assembly Loader loaded assembly from location: 'C:\Program Files\Mono-1.2.5\lib\mono\gac\Mono.Posix\2.0.0.0__0738eb9f132ed756\Mono.Posix.dll'. Mono-INFO: Config attempting to parse: 'C:\Program Files\Mono-1.2.5\lib\mono\gac\Mono.Posix\2.0.0.0__0738eb9f132ed756\Mono.Posix.dll.config'. Mono-INFO: Config attempting to parse: 'C:\Program Files\Mono-1.2.5\lib\..\etc\mono\assemblies\Mono.Posix\Mono.Posix.config'. Mono-INFO: Assembly Ref addref System.Windows.Forms 00196660 -> Mono.Posix 001922E8: 2 Mono-INFO: DllImport attempting to load: 'user32.dll'. Mono-INFO: DllImport loading location: 'user32.dll.dll'. Stacktrace: at System.Windows.Forms.XplatUIWin32.GetInstance () <0xffffffff> at System.Windows.Forms.XplatUIWin32.GetInstance () <0x00020> at System.Windows.Forms.XplatUI..cctor () <0x000b8> at (wrapper runtime-invoke) System.Windows.Forms.Application.runtime_invoke_void (object,intptr,intptr,intptr) <0xffffffff> at System.Windows.Forms.Application.EnableVisualStyles () <0xffffffff> at System.Windows.Forms.Application.EnableVisualStyles () <0x00008> at crc32_gui.Program.Main () <0x00008> at (wrapper runtime-invoke) crc32_gui.Program.runtime_invoke_void (object,intptr,intptr,intptr) <0xffffffff> --- snip --- Notice the message "DllImport loading location: 'user32.dll.dll'." Further search in mono source reveals this comes from mono/mono/metadata/loader.c:mono_lookup_pinvoke_call() which tries to load the module using a variety of names. This function calls mono/mono/utils/mono-dl.c:mono_dl_build_path() to return possible file names of the library. Well mono_dl_build_path() assumes the library parameter is the "base name of a library". Which is of course not the case: full name supplied instead. ".dll" is mistakenly appended for all assemblies. Next the module should be loaded: mono_lookup_pinvoke_call() -> cached_module_load() -> mono_dl_open() It fails loading dll (LL_SO_OPEN -> w32_load_module -> LoadLibrary()). Of course: user32.dll.dll wont work. It tries then again with ".la" suffix appended and fails again. Now the interesting part, the error handling. When an error is encountered, LL_SO_ERROR() is called which should return a formatted (system) error message (pointer to buffer). LL_SO_ERROR maps to "w32_dlerror" which is this code: --- snip mono-1-2-5/mono/mono/utils/mono-dl.c --- static char* w32_dlerror (void) { char* ret = NULL; wchar_t* buf = NULL; DWORD code = GetLastError (); if (FormatMessage (FORMAT_MESSAGE_FROM_SYSTEM | FORMAT_MESSAGE_ALLOCATE_BUFFER, NULL, code, MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT), buf, 0, NULL)) { ret = g_utf16_to_utf8 (buf, wcslen(buf), NULL, NULL, NULL); LocalFree (buf); } return ret; } --- snip mono-1-2-5/mono/mono/utils/mono-dl.c --- Can you spot the bug? Hint: FORMAT_MESSAGE_ALLOCATE_BUFFER tells the callee to allocate memory. Well, try to store the returned buffer pointer in nirvana and fail miserably ;-) So actually it's both: a mono and a wine bug. Mono should actually do FormatMessage( ...., &buf, ...) and Wine should actually watch for supplied NULL ptrs in FormatMessageA/W() before trying to access them (copy). Now you might think "ok, that's it". No it isnt over yet ;-) After i quick-fixed wine's FormatMessageA/W to handle buf == NULL case (returning 0 length) mono crashed again. Well mono assumes if any error occurs a system generated error message must be returned. The logging mechanism depends on that. If it fails somehow, like the bug in mono code itself, which prevents FormatMessageA/W() from returning valid error msg buffer it crashes by deref null pointer. --- snip pseudo code --- ret = call_some_native_func( ... &error_msg) if( !ret) { mono_trace( "... %s", error_msg); g_free (error_msg); } --- snip pseudo code --- So there is currently no way to get around these issues without fixing mono source itself. Wine should fix the FormatMessageA/W() and msvcrt._wspawnvp() issues. FOR THE RECORD: the code flow and issues are essentially the same on native windows platform (except for the FormatMessage bug). Start console (cmd.exe) there. Enable logging (set MONO_LOG_MASK=debug). Start mono.exe with some .net app (i used simple 2.0 .net app generated by VC2005/C#) and see it die. For more fun, enable AOT cache (set MONO_AOT_CACHE=1). Die.

[Bug 6183] NFS MW crashed when sound is on in winecfg

http://bugs.winehq.org/show_bug.cgi?id=6183 guebby(a)gmail.com changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |guebby(a)gmail.com --- Comment #18 from guebby(a)gmail.com 2007-09-15 14:58:15 --- I can play with sound but without the car's engine sound, by deleting or removing SOUND/ENGINE directory. Anyway, when the car jumps in slow motion (also with sound) the game crashes too, even deleting the entire SOUND directory. With engine's sound, some cars can "stay" without crashing the game if you do not accelerate. With the Porsche 911 Turbo S, the game crashes when revs pass 4000 rpm. With the Corvette it happens before 1000 rpm. My Wine version is 0.9.45 on a Gentoo Linux 2.6.20 x86_64 single core. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching all bug changes.
