[Bug middle-end/37788] New: [4.4 regression] ICE with variable declaration in loop and -fmudflap

[reichelt at gcc dot gnu dot org]

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.
