Bug ID: 58596
Summary: [4.8/4.9 Regression] [c++11] ICE with decltype in
non-static data member initializer
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++11") triggers an ICE since
GCC 4.8.0:
==============================================
struct A
{
int i = [] { return decltype(i)(); }();
};
==============================================
bug.cc: In lambda function:
bug.cc:3:32: internal compiler error: Segmentation fault
int i = [] { return decltype(i)(); }();
