https://bugs.winehq.org/show_bug.cgi?id=39570 Bug ID: 39570 Summary: Multiple application crash handlers fail to load symbol information using 'dbghelp.SymLoadModule64', reporting 'dbghelp:validate_addr64 Unsupported address 0xfffffffffxxxxxxx' Product: Wine Version: 1.7.54 Hardware: x86-64 OS: Linux Status: NEW Severity: normal Priority: P2 Component: dbghelp Assignee: wine-bugs(a)winehq.org Reporter: focht(a)gmx.net Distribution: --- Hello folks, the issue/question was raised in https://bugs.winehq.org/show_bug.cgi?id=32237#c15 --- quote --- I did try 2012 this time and I end up crashing fixme:dbghelp:validate_addr64 Unsupported address fffffffff33a0000 err:seh:raise_exception Unhandled exception code c0000005 flags 0 addr 0x7bc3db51 What's wrong with the address? --- quote --- Searching the Internet reveals this pattern/message many times - also in Wine Bugzilla - but no or even incorrect explanation - until now ;-) On 64-bit Linux machines, the Wine loader allows 32-bit dlls being mapped at high >2GB, >3GB address ranges in 32-bit processes, not having certain (design) restrictions of 32-bit process address space layout on 64-bit Windows machines (even with /LARGEADDRESSWARE).

'dbghelp.SymLoadModule64' is called by the custom crash handler. Source: https://source.winehq.org/git/wine.git/blob/1fa7710ff92dd9555b2b4753e22ce5f… --- snip --- 656 DWORD64 WINAPI SymLoadModule64(HANDLE hProcess, HANDLE hFile, PCSTR ImageName, 657 PCSTR ModuleName, DWORD64 BaseOfDll, DWORD SizeOfDll) 658 { 659 return SymLoadModuleEx(hProcess, hFile, ImageName, ModuleName, BaseOfDll, SizeOfDll, 660 NULL, 0); 661 } --- snip --- So how does high DWORD of 'BaseOfDll' parameter get the 0xffffffff value? A few caller frames up in the app crash handler: --- snip --- ... 005F06D6 8B55 D0 MOV EDX,DWORD PTR SS:[EBP-30] 005F06D9 8B45 CC MOV EAX,DWORD PTR SS:[EBP-34] 005F06DC 8B4D F8 MOV ECX,DWORD PTR SS:[EBP-8] 005F06DF 52 PUSH EDX 005F06E0 99 CDQ 005F06E1 52 PUSH EDX ; high DWORD BaseOfDll 005F06E2 50 PUSH EAX ; low DWORD BaseOfDll 005F06E3 8B45 FC MOV EAX,DWORD PTR SS:[EBP-4] 005F06E6 50 PUSH EAX 005F06E7 51 PUSH ECX 005F06E8 8B4D E8 MOV ECX,DWORD PTR SS:[EBP-18] 005F06EB 56 PUSH ESI 005F06EC E8 EFF7FFFF CALL A_Slower.005EFEE0 ... --- snip --- 'winex11.drv' -> 0xf72f0000 Since the highest bit in low 32-bit 'BaseOfDll' DWORD is set, the 'CDQ' instruction copies the sign (bit 31) of the value in the EAX register into every bit position in the EDX register. Voila - you get the 0xffffffff EDX value which is then propagated through the caller chain as high 32-bit 'BaseOfDll' DWORD to 'dbghelp.SymLoadModule64', leading to symbol load failure and fixme/warning messages. This should be fixed, allowing symbol information even for dlls mapped in high address range to be loaded. $ wine --version wine-1.7.54-261-g61c49bd Regards -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 40502] New: Global objects constructors fail when invoking standard libs
by wine-bugs＠winehq.org 24 Apr '20

https://bugs.winehq.org/show_bug.cgi?id=40502 Bug ID: 40502 Summary: Global objects constructors fail when invoking standard libs Product: Wine Version: 1.8.1 Hardware: x86 OS: Linux Status: UNCONFIRMED Severity: major Priority: P2 Component: winelib Assignee: wine-bugs(a)winehq.org Reporter: mirko.ortensi(a)gmail.com Distribution: --- I managed to recompile and link my win32 application but at execution time, it crashes because of a segmentation fault where memset (or the bare printf("HELLO")) is invoked in the global object constructor (any call to standard C library is enough to trigger the crash). The global object is built in the stack, then it seems that at launch time my object constructor is called before C Standard Library is ready. Now, as a workaround I can declare a pointer to global object and instantiate it in the main (tested, it works)...though...this is something I'd like to avoid to keep the code as original as possible. Removing the global objects, everything works like a charm. As far as I understand, global object constructors are called after Wine infrastructure is ready to go, though I have doubts now regarding C Standard Library. (Please check 8.3.3. Starting a Winelib process https://www.winehq.org/docs/winedev-guide/x3172) This code reproduces the error: #include <stdio.h> class Printer { public: Printer(){printf("HI\n");} }; Printer p; int main(void) { return 0; } The issue is reproduced by this code linking to msvcrt: wineg++ -mno-cygwin issue.cpp -o issue Linking to system libs, this code does not reproduce the issue. wineg++ issue.cpp -o issue Now, in my code (pretty big software I am porting to Linux) I still need to isolate root cause, issue is reproduced even linking against system libraries (not Wine's msvcrt, then). Anyway, I think there's a bug somewhere when linking to msvcrt even in this silly piece of code. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
