SIGFPE - EqFader::updateVuMeters()

[zonkmachine]

System Information

Ubuntu 22.04

LMMS Version(s)

1036144

Bug Summary

SIGFPE received in project compiled with cmake .. -DCMAKE_BUILD_TYPE=Debug -DWANT_DEBUG_FPE=ON

I believe I was trying to switch to an old saved project from another after playing the previous one for a minute or so.

Steps To Reproduce

This was a stray SIGFPE and I haven't been able to recreate it but the method would be:
Load a project, play it, and then open the demo project (below).
