[Bug tree-optimization/22484] New: ICE: verify_stmts failed with -O3

[micis at gmx dot de]

When I compile ace542 with the actual snapshot of gcc41 I get an ICE when I 
use -O3.

The last snapshot which works is gcc-4.1-20050528, the first that fails is gcc-
4.1-20050604.

Confirmed. Reduced testcase (compile with -O3):

======================================
struct A { ~A(); };
typedef bool B;

bool foo();

bool bar(A&)
{
  B b = true;

  for (int i = 0; i < 2 && b; ++i)
    b = foo();

  return b;
}

void baz()
{
  A a;
  if (bar(a)) foo();
}
======================================

The strange thing is that the typedef is really necessary.

The problem only affects mainline.

Found the problem, we should be removing the cast as it is useless.
Fixing.
