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).
