WINEDEBUG=+seh,+DllOverrides wine SMathStudio_Desktop.exe >>
/tmp/output_tid.txt 2>&1

wine-5.0 (Staging), Fedora 31 release on x86_64 machine.

Smath (https://en.smath.com/view/SMathStudio/summary), a very useful free
MathCAD-like program crashes at startup.

Installation of

SMathStudioDesktop.0_99_7251.Setup.msi

completes, and the program runs fine if started as such:

WINEDEBUG=+relay wine SMathStudio_Desktop.exe

However, if started as:
wine SMathStudio_Desktop.exe
WINEDEBUG=+seh,+DllOverrides wine SMathStudio_Desktop.exe
WINEDEBUG=+tid,+DllOverrides wine SMathStudio_Desktop.exe

I get a Segmentation fault (core dumped).
