Hello, not being maintainer I tried to reproduce this issue. It looks like another case of pointer truncation due to "implicit declaration of function" in various files.
Attached patch adds an include to gdk/gdk.h in a global header file. With it applied no implicit declarations remain and the crash does not happen anymore. Kind regards, Bernhard Program terminated with signal SIGSEGV, Segmentation fault. #0 0x00007fa80d502566 in IA__gdk_gc_set_foreground (gc=0x26e37730, color=color@entry=0x563726dea028) at ./gdk/gdkgc.c:394 394 ./gdk/gdkgc.c: Datei oder Verzeichnis nicht gefunden.
