The following invalid code snippets triggers an ICE since GCC 4.3.0:
=================================
void foo()
{
({ i; ({ i; }); 0; });
}
=================================
bug.cc: In function 'void foo()':
bug.cc:3: error: 'i' was not declared in this scope
gimplification failed:
<statement_list 0x402277c4
type <void_type 0x401a94e0 void VOID
align 8 symtab 0 alias set -1 canonical type 0x401a94e0

bug.cc:3: internal compiler error: gimplification failed
