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 Wine 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:
Code:
#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:
Code:
g++ -c -fPIC t.cpp
/home/mkk/wine-git_64/tools/winegcc/wineg++ -B/home/mkk/wine-git_64/tools/winebuild -o tt t.o
run as:
Code:
wine tt.exe.so
Prints 'start', then crashes.
Any idea how to solve this problem?
