Segmentation Fault when exiting FreeSSM that is compiled in Ubuntu under WSL

[jmbach]

I have a windows 11 computer with WSL2 that I installed Ubuntu

I have installed qt5-default and qttools5-dev-tools.

Everything compiles fine.

Run sudo ./FreeSSM and loads fine with two warnings.
QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root'
libpng warning: iCCP: too many profiles

Have not used it with any adapters attached yet. Just starting and exiting the program produces the Segmentation fault.

Additional information. This error does not happen when I run FreeSSM the first time after starting up Ubuntu but occurs the second time I run FreeSSM and every time thereafter.

Don't do that, WSL is most likely the culprit.
If you are running Windows, why don't you compile/run FreeSSM on Windows directly ?
Alternatively (if you are forced to run Linux on top of Windows), install Linux on a virtual machine.

Run sudo ./FreeSSM and loads fine with two warnings.

Why do you run FreeSSM as root ? That's neither required nor recommended.

With some distros, normal users do not have access to serial ports by default.
In that case, just add the user to group "dialout".

QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root'

Nothing to worry about.

Have not used it with any adapters attached yet. Just starting and exiting the program produces the Segmentation fault.

If I had to guess:
FreeSSM uses a shared memory object (QSharedMemory) to avoid running multiple instances of FreeSSM.
I wouldn't be surprised if WSL doesn't handle it correctly.
Try commenting out lines 90 to 102 in src/main.cpp to find out.
