Subject: [Bug c++/18545] New: [3.4/4.0 regression] ICE when returning undefined type
Date: Thu, 18 Nov 2004 16:03:00 -0000 [thread overview]
Message-ID: <20041118160250.18545.reichelt@gcc.gnu.org> (raw)
The following invalid code snippet crashes the C++ frontend:
===================================================
struct A;
A foo()
{
A a;
return a;
}
===================================================
bug.cc: In function 'A foo()':
bug.cc:7: error: return type 'struct A' is incomplete
bug.cc:9: error: aggregate 'A a' has incomplete type and cannot be defined
bug.cc:10: internal compiler error: tree check: expected class 'type', have
'exceptional' (error_mark) in check_return_expr, at cp/typeck.c:6296
Please submit a full bug report, [etc.]
The bug is present since gcc 3.4.0.
Looks like it was introduced with the new parser:
: Search converges between 2002-12-14-trunk (#159) and 2002-12-29-trunk (#160).
