[Bug c/34982] New: [4.3 regression] calling a function with undefined parameters causes segmentation fault at -O1 or higher

[bero at arklinux dot org]

The following (admittedly ugly) piece of code works on older gccs, and
segfaults on 4.3:


#include <assert.h>
#include <string.h>

static void something();

int main(int argc, char **argv) {
        something("test");
}

static void something(const char *whatever) {
        assert(!strcmp(whatever, "test"));
}



Changing the initial declaration of something() to static void something(char
*whatever) makes the problem go away.
