SUMMARY
Filelight for a while has been crashing on launch (definitely already did on
21.12 as well), seemingly with SIGSEGV.

Backtrace:


Thread 1 "filelight" received signal SIGSEGV, Segmentation fault.
0x000055555556bed2 in sincos (angleRadians=1.014472627721704,
Sin=0x7fffff7ff038, Cos=0x7fffff7ff030) at

(this goes on forever)

STEPS TO REPRODUCE
1. Launch Filelight

OBSERVED RESULT
Filelight crashes just after the window has launched

EXPECTED RESULT
Filelight to not crash, obviously

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Alpine Linux edge
(available in About System)
KDE Plasma Version: 5.24.4
KDE Frameworks Version: 5.93.0
Qt Version: 5.15.3 with KDE patches

ADDITIONAL INFORMATION
This system uses Musl libc which seems to be where it goes wrong.
https://invent.kde.org/utilities/filelight/-/blob/master/src/radialMap/sincos.h
reveals it checks if it's not running on Glibc which in this case is true.
qmath.h is provided by qt5-qtbase, but I'm not sure it's looking at the right
location for it.
