The following invalid code snippet triggers an ICE on mainline:
===============================
void foo()
{
__decltype A::foo();
}
===============================
bug.cc: In function 'void foo()':
bug.cc:3: error: 'A' was not declared in this scope
bug.cc:3: internal compiler error: tree check: expected class 'type', have
'exceptional' (error_mark) in build_reference_type_for_mode, at tree.c:5463
Please submit a full bug report, [etc.]
The problem appeared between 2007-07-16 and 2007-08-15, presumably with
the introduction of decltype:
2007-07-27 Douglas Gregor <[EMAIL PROTECTED]>
* typeck.c (structural_comptypes): Compare DECLTYPE_TYPE nodes.
* cp-tree.def (DECLTYPE_TYPE): New.
* error.c (dump_type): Dump DECLTYPE_TYPE nodes.
