Summary: internal compiler error: Segmentation fault (in
-std=c++0x mode)
Product: gcc
Version: 4.6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: gcc@abeckmann.de
The following piece of invalid code gives an ICE SIGSEGV when compiling in
c++0x mode:
===== 8< =====
template < class >
struct
pair
{
:
first ()
===== >8 =====

depend on a template parameter, so a declaration of ‘first’ must be available

your code, but allowing the use of an undeclared name is deprecated)
