--- Comment #3 from Martin Uecker <muecker at gwdg dot de> ---
Here is another example which fails on armel
extern _Complex float g(int N, int dims[N]);
void f(void)
{
int dims[1];
_Complex float val = g(1, dims);
}
during RTL pass: expand
BUG.c: In function 'f':
BUG.c:10:30: internal compiler error: Segmentation fault
10 | _Complex float val = g(1, dims);
