<pre>Compiling the following code with Apple's LLVM 6.0 (Xcvode 6) hangs the clang.
Optimisation must be enabled.
Running "clang -O1 -c foo.c" on the following code hangs the clang forever.
This doesn't happen with original LLVM and other LLVM versions.
void foo()
{
int a = 1;
while (1)
{
if (a)
{
label:
a += 2;
a *= (long)&&label;
}
}
}</pre>
