I can reproduce it while using a native or cross compiler targeting mips and while generating code for big or little endian. I could also reproduce it on targets for linux and for elf. % cat q.c swapfunc(char *a , char *b , int n , int swaptype) { long i = (n) / sizeof (char); char *pi = (char *) (a); char *pj = (char *) (b); do { *pi++ = *pj; } while (--i > 0); } qsort(void *a) { char *pb; int r; int swaptype; swapfunc(a, pb - r, r, swaptype); } % obj*/gcc/initial/gcc/cc1 -quiet -mel -O2 -mips16 q.c q.c: In function ‘qsort’: q.c:10:1: internal compiler error: Floating point exception qsort(void *a) ^ Please submit a full bug report, with preprocessed source if appropriate.
