This did indeed break CI because s->argv is an array of *char:
../semihosting/config.c:101:17: error: assignment to ‘const char **’ from incompatible pointer type ‘void **’ [-Werror=incompatible-pointer-types]
101 | s->argv = g_renew(void *, s->argv, s->argc + 1);
| ^
cc1: all warnings being treated as errors
So it did the job of type checking but failed to build ;-)
