            Bug ID: 58672
           Summary: ICE with thread_local and variable of broken class
           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 invalid code snippet (compiled with "-std=c++11") triggers an ICE
since GCC 4.8.0 (when thread_local was introduced):

==========================
struct A
{
  A(int);
  i;
};

thread_local A a(0);
==========================

bug.cc:4:3: error: 'i' does not name a type
   i;
   ^
bug.cc: In function 'void __tls_init()':
bug.cc:7:16: internal compiler error: Segmentation fault
 thread_local A a(0);
                ^
