>Description:
The ICE occurs when the illegal syntax 'throw Exc;' is used as a *simple*statement* within an if or while construct.
It does not occur, however, when the throw statement is placed in {}s.

Compiler output:
test1.cc: In function `int main ()':
test1.cc:4: parse error before `;'
test1.cc:5: parse error before `;'
test1.cc:6: Internal error #122.
test1.cc:6: Internal compiler error in finish_function, at 
../gcc/cp/decl.c:14409

>How-To-Repeat:
struct Exc {};

int main() {
    if (1) {throw Exc;} // This is OK
    if (1) throw Exc;   // This is ICEish
}
