The test case from bug 40012 still fails in current mainline @149059 in 32-bit
mode:
--- cut ---
struct list_s {
struct list_s* next;
};
typedef struct list_s list;
void f1(void*, list*);
int
f0(void* a,
void* b,
void* c,
list* d)
{
list* problem;
for(problem = d; problem; problem = problem->next) {
int variable = 0;
f1(c, problem);
}
return (0);
}
int main()
{
list a3 = { 0 };
f0(0, 0, 0, &a3);
return 0;
}
void f1(void*a, list*b) { }
--- cut ---

Note mismatch between where GDB thinks &a3 is and the actual address.
[AFAICT, this is currently causing 300+ failures in the GDB test suite.]
