Bug ID: 48442 Summary: MPGUI crash on start in MSVCRT__wctomb_s_l in msvcr100 Product: Wine Version: 5.0-rc4 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: msvcrt Assignee: wine-bugs@winehq.org Reporter: lorenzofer@live.it Distribution: ---

Created attachment 66220 --> https://bugs.winehq.org/attachment.cgi?id=66220 stacktrace

Hi, MPGUI (a C++/CLI application, so C++ app that use the .NET runtime )crash on start with a Unhandled exception: page fault on read access to 0x00000020 in 32-bit code (0x7c6e61a0).

PArt of the stacktrace: 0 0x7c6e61a0 MSVCRT__wctomb_s_l+0x1180() in msvcr100 (0x0032f378) 1 0x7c6e87f0 MSVCRT_vsnprintf+0x3f() in msvcr100 (0x0032f3c8) 2 0x7c6e8952 MSVCRT_sprintf_s+0x21() in msvcr100 (0x0032f3f8)

0x7c6e61a0 MSVCRT__wctomb_s_l+0x1180 in msvcr100: movzbl 0x0(%edi),%eax

This part of the stacktrace suggest that native dotnet may be a workaround:

10 0x6c54c5ee mono_jit_runtime_invoke+0x46d(exc=<is not available>) [Z:\vagrant\mono\mono\mini\mini-runtime.c:3184] in libmono-2.0-x86 (0x005f6b48) 11 0x6c71da32 object_new_handle_common_tail+0x1d1(o=<is not available>, klass=<is not available>, error=<is not available>) [Z:\vagrant\mono\mono\metadata\object.c:3029] in libmono-2.0-x86 (0x00000000) 12 0x6c722105 mono_runtime_object_init+0xd4() [Z:\vagrant\mono\mono\metadata\object.c:5151] in libmono-2.0-x86 (0x00000000) 13 0x6c5a3372 mono_jit_exec+0x191() [Z:\vagrant\mono\mono\mini\driver.c:1325]

Full stacktrace attached.

Prefix is new. 32bit Wine Log is empty.

--- Comment #2 from Lorenzo Ferrillo lorenzofer@live.it --- Confirm installing dontet452 fix the crash.

So it seems that the wine-mono runtime may do an invalid call in this circumstance, or the msvcr100 doesn't handle correctly an edge case.

Yes just start MPGUI should trigger the bug.

--- Comment #5 from Piotr Caban piotr.caban@gmail.com --- It crashes in the same way when native msvcr100 is used. sprintf_s is called with incorrect arguments. Changing component to unknown.

Still present in wine-6.8 with wine-mono-6.1.1. 'winetricks -q dotnet40' is enough to work around.

--- Comment #7 from Gijs Vermeulen gijsvrm@gmail.com --- Marking as a wine-mono bug as native dotnet fixes it and native msvcr100 makes no difference. If this is not the right assumption to make, let me know.

Do you prefers to have an issue on github for this?

--- Comment #10 from Esme Povirk madewokherd@gmail.com --- It's too complex to point to just one place, but the most relevant parts are probably marshal.c and marshal-ilgen.c. You may find MONO_VERBOSE_METHOD=sprintf_s to be a useful tool, as it will show the output of the code generation process, as well as the function address which can be used to show disassembly if you have winedbg attached.

--- Comment #11 from Esme Povirk madewokherd@gmail.com --- I get a different error:

Unhandled Exception: System.Runtime.InteropServices.MarshalDirectiveException: Type System.ArgIterator which is passed to unmanaged code must have a StructLayout attribute. at (wrapper managed-to-native) <Module>.vsprintf_s(sbyte modopt(System.Runtime.CompilerServices.IsSignUnspecifiedByte)*,uint,sbyte modopt(System.Runtime.CompilerServices.IsSignUnspecifiedByte) modopt(System.Runtime.CompilerServices.IsConst)*,System.ArgIterator) at <Module>.llLogger.WriteNextLine (llLogger* , System.Int32 _level, System.SByte* _format) [0x00077] in <d6ddfbb4dbaf4ec1a1dec038c2023081>:0 at <Module>.llAddGame.Exec (llAddGame* ) [0x0000c] in <d6ddfbb4dbaf4ec1a1dec038c2023081>:0

Corresponding code on GitHub: https://github.com/Gruftikus/lltool/blob/master/src/lllogger.cpp#L54

Based on a wrapper log it seems like it's been able to call sprintf_s without crashing, but I can't tell if the particular call that crashed for others is working now.

--- Comment #12 from Esme Povirk madewokherd@gmail.com --- I think this requires an implementation of marshaling ArgIterator to va_list.

How hard that is probably depends on the ABI for va_list. I can't seem to find any documentation for it.

--- Comment #13 from Esme Povirk madewokherd@gmail.com ---

...

From compiling a test program and looking at disassembly, it seems like va_list

on Windows is just a pointer to a buffer containing the arguments. That leaves a lot of ambiguity in terms of how things are packed, but in most cases they're likely to be pointer-sized.

The program starts with those changes, but since I don't have any games or mods to work with I can't test it.
