Bug ID: 48875 Summary: Segfault when calling InitializeCriticalSection (Kernel32.dll) during static initialization Product: Wine Version: 5.5 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: winelib Assignee: wine-bugs@winehq.org Reporter: winehq@twig.hk Distribution: ---

Created attachment 66810 --> https://bugs.winehq.org/attachment.cgi?id=66810 Example Code that causes segfault

When InitializeCriticalSection is called during static initialization, the program segfaults. When it's removed, or moved into WinMain, it does not.

Code Snippet: #include <windows.h>

CRITICAL_SECTION crit;

struct Critical{ Critical(){ InitializeCriticalSection(&crit); } };

static Critical critical;

...Snip...

The code was compiled and run with: wineg++ simple.cpp && wine a.out.so

And can you a give the URL of a freely downloadable application showing the problem?

I tried with 5.5, but couldn't work out how to get a readable backtrace from it, it still crashes and the segfault memory address is still a bit too small.

I have attached the source of the example program i have been using for testing?

Created attachment 66812 [details] Simpler code that still causes the segfault

I tried this, built as:

x86_64-w64-mingw32-gcc bug48875.cpp -o bug48875.exe

and I don't see any crashes. Could you attach pre-built exe? Or build instructions.

It's using wine lib, so to compile and run:

wineg++ simple.cpp && wine a.out.so

That's true. It was there so you can show that it's not InitializeCriticalSection causing the crash.

New subject: [Bug 48875] Winelib applications can't call the Wine API during static constructors

https://bugs.winehq.org/show_bug.cgi?id=48875

Fabian Maurer dark.shadow4@web.de changed:

--- Comment #11 from Fabian Maurer dark.shadow4@web.de --- Okay, so the problem is indeed the program being a .so file (winelib) instead of an .exe (MinGW).

When the program is loaded, during wine_dlopen, the static constructors are run. But only during main, wine gets a chance to fixup the imports by calling LdrInitializeThunk.

So during static constructors no wine code can be called, since the imports are not fixed up yet.

No idea how to solve this though.

Marking dupe of already existing bug 40502.
