Bug #: 51421
Summary: [c++0x] ICE with invalid use of auto
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: reichelt@gcc.gnu.org
The following invalid code snippet triggers an ICE since GCC 4.4.0:
=====================
int foo(int);
void bar()
{
auto i = foo(i);
}
=====================
bug.cc: In function 'void bar()':
bug.cc:5:17: internal compiler error: tree check: expected record_type or
union_type or qual_union_type, have template_type_parm in lookup_conversions,
at cp/search.c:2499
Please submit a full bug report, [etc.]
A slightly different example triggers an ICE in a different position:
=====================
struct A {};
A foo(A);
void bar()
{
auto a = foo(a);
}
=====================
bug.cc: In function 'void bar()':
bug.cc:7:17: internal compiler error: tree check: expected record_type or
union_type or qual_union_type, have template_type_parm in lookup_base, at
cp/search.c:212
Please submit a full bug report, [etc.]

In mainline we now produce useful diagnostics before ICEing, likely the ICE
itself is much easier to fix.
