[Bug middle-end/31127] New: [4.3 regression] ICE in cse_find_path, at cse.c:5930

[gerald at pfeifer dot com]

I have destilled the following small testcase from Wine, specifically
dlls/advapi32/security.c.

Compiling this with -O2 results in an ICE in cse_find_path at cse.c:5930.

void ParseStringSidToSid(char *s, int* p) {
    int i = 0;

    while (*s) {
        while (*s && *s != '-')
            s++;
        if (*s== '-')
            s++;

        p[i++] = *s;
    }
}
