Public bug reported:
Binary package hint: spu-gcc
Following program behaves incorrectly when compiled with -O1 or -O2 (-O0
and -O3 shows correct behaviour).
----
#include <stdio.h>
#include <stdlib.h>
struct mystruct_t {
int dimension;
};
struct mystruct_t *s;
void foo (void)
{
printf("dimension = %d (should be 1)\n", s->dimension);
}
int main (void)
{
s = malloc(sizeof(struct mystruct_t));
s->dimension = 1;
foo();
return 0;
}
