<pre>Compiling the following snippet will make clang crash.
The getTypeInfo function is calling itself endlessly
template <typename T_CHAR> void foo(){
T_CHAR buffer[32];
((char*)buffer)[0] = 'A';
}
void f(){
foo<char>();
}
You can see the stack trace here and test it against various clang versions
