Bug ID: 60250
Summary: [4.9 Regression] [c++1y] ICE using lambda for array
size
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Keywords: ice-on-valid-code
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: reichelt at gcc dot gnu.org
The following valid code snippet (compiled with "-std=c++1y") triggers
an ICE on trunk. The code compiles fine, if it is compiled with
"-std=c++11".
====================================
template<typename> void foo()
{
typedef int T[ ([](){ return 1; }()) ];
}
====================================
bug.cc: In function 'void foo()':
bug.cc:3:40: internal compiler error: Segmentation fault
typedef int T[ ([](){ return 1; }()) ];
