--- Comment #11 from Martin Liška <marxin at gcc dot gnu.org> ---
But yes, with ulimit -s 512, one can reduce it to:
$ cat pr103231.c
long g_1496_BK8K8el_2738;
int fn1_l_1522;
int fn1_l_2664;
long fn1_l_1761;
unsigned int fn1_l_1812;
int fn1_l_2189;
int fn1_by;
int fn1_l_2688;
short fn1_l_1852;
short fn1_l_2352;
void fn1() {
unsigned l_2456;
LABEL_5959g:
__builtin_printf("l_2456=%llu\n", l_2456);
LABEL_TaTak:
if (fn1_by)
if (fn1_l_2189) goto LABEL_5959g;
int BK8K8hl_2189 = fn1_l_2352 * (~fn1_l_1852 & g_1496_BK8K8el_2738);
short dg = l_2456 & fn1_l_1761;
l_2456 = dg;
if (fn1_l_1522) fn1_l_1761 = ~BK8K8hl_2189;
short Bm9m9El_1852 = ~(~0 && fn1_l_2688);
unsigned Bm9m9Fl_1522 = -Bm9m9El_1852;
if (fn1_l_1812) fn1_l_1852 = ~fn1_l_2664 ^ Bm9m9Fl_1522;
goto LABEL_TaTak;
}
with the following back-trace:
