New issue by jorgenatz on void-packages repository

https://github.com/void-linux/void-packages/issues/12595
Description: ### System

* xuname:  
  Void 4.19.48_1 x86_64-musl GenuineIntel notuptodate rF
* package:  
  freecad

### Expected behavior
When 
`$  FreeCAD`
is typed, I had expected the program to start as normal, showing a splash screen until subsequently opening a window.

### Actual behavior
When running, this error is produced:
```
Error compiling builtin: 
Fatal error compiling builtin function 'apply': Program received signal SIGSEGV, Segmentation fault.
sorry, no backtrace on musl libc
```
The startup splash screen is shown with a variety of intialization messages before the crash.

This is the entire output:
```
FreeCAD 0.18.2, Libs: 0.18.2R1_voidlinux
