The following valid code snippet triggers an ICE on mainline when compiled
with "-fmudflap -O -g":
==================
struct A
{
A();
};
void foo()
{
while (true)
A a;
}
==================
bug.cc: In function 'void foo()':
bug.cc:10: internal compiler error: tree check: expected block, have
function_decl in change_scope, at cfglayout.c:420
Please submit a full bug report, [etc.]
This is a recent regression, introduced between 2008-09-29 and 2008-10-08.
