Subject: [Bug c++/18177] New: [4.0 regression] ICE with const_cast for undeclared variable
X-Bugzilla-Reason: CC
X-SW-Source: 2004-10/txt/msg03317.txt.bz2
List-Id: <gcc-bugs.sourceware.org>

The following invalid code snippet causes an ICE when compiled with mainline:

=============================
void foo()
{
    X;
    const_cast<int&>(X);
}
=============================

bug.cc: In function `void foo()':
bug.cc:3: error: 'X' was not declared in this scope
bug.cc:4: internal compiler error: tree check: expected class 'type', have
'exceptional' (error_mark) in build_pointer_type_for_mode, at tree.c:4118
Please submit a full bug report, [etc.]

The regression appeared in March 2004:
: Search converges between 2004-03-01-trunk (#446) and 2004-04-01-trunk (#447).
