Bug ID: 58560
Summary: [4.7/4.8/4.9 Regression] ICE with auto in typedef
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: reichelt at gcc dot gnu.org
The following code snippet (compiled with "-std=c++0x") triggers an ICE since
GCC 4.7.0:
========================
typedef auto T;
void foo() { T(); }
========================
bug.cc:1:14: error: typedef declared 'auto'
typedef auto T;
^
bug.cc: In function 'void foo()':
bug.cc:3:16: internal compiler error: tree check: expected class 'type', have
'exceptional' (error_mark) in build_value_init_noctor, at cp/init.c:377
void foo() { T(); }

Fixed for 4.9.0. I don't think it's worth fixing in 4.7 and 4.8.
