Public bug reported:
This problem appears only on Ubuntu 20.04 with Wine 5.0 installed from
Ubuntu repository. If I build Wine 5.0 myself or install Wine 4.0.4 from
WineHQ repository, then there is no problem, so I assume the problem is
in Ubuntu 20.04 build of Wine.
I have written a shared library for our application using Winelib project,
which calls native Linux API. C++ is used. Crash happens on first C++ exception
thrown.
App which shows the problem:
#include <stdexcept>
#include <stdio.h>
int main() {
printf("start\n");
try {
throw std::runtime_error("desc");
} catch (std::exception &ex) {
printf("in catch\n");
}
printf("end\n");
}
built with:
g++ -c -fPIC t.cpp
../wine-git_64/tools/winegcc/wineg++ -m64 -B../wine-git_64/tools/winebuild
-L ../wine-git_64/dlls/kernel32/ -L ../wine-git_64/dlls/advapi32/ -L
../wine-git_64/dlls/user32/ -L ../wine-git_64/dlls/winecrt0 -L
../wine-git_64/dlls/ntdll/ -L ../wine-git_64/libs/wine -o tt t.o
where '../wine-git_64/' is directory where I cloned and built Wine64 5.0 stable
to get wineg++ linker.
Run the application as:
wine tt.exe.so
It prints 'start', then it crashes. The application crashes in Wine
(Wine dialog pops-up), so I think Ubuntu is not aware of this crash.
Contents of Wine crash dialog (backtrace.txt):
Unhandled exception: assertion failed, invalid program stack in 64-bit code
(0x00007fa3b70d118b).
