native shared library crashes if C++ exceptions are used on Ubuntu Wine build

[markok3-14]

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:

         
#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
    /home/mkk/wine-git_64/tools/winegcc/wineg++ -B/home/mkk/wine-git_64/tools/winebuild -o tt t.o

run as:

   wine tt.exe.so

Prints 'start', then crashes.
Any idea how to solve this problem?

if this issues is only present on Ubuntu repo build, it is clearly ubuntu packaging issue of sorts. i would report it on launchpad.
