Clang output (includes stack trace)
Test case:
struct Infinite {
struct Infinite nested;
};
void f(struct Infinite* x) { *x = 0; }
You can literally assign *anything* to *x, and the crash will occur.
Preprocessed source file (this is mostly insignificant in the test case for
obvious reasons), run script, and stack trace (in seg.log) attached.</pre>
