            Bug ID: 58671
           Summary: ICE with thread_local and self-referential variable
                    initialization
           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 valid code line(compiled with "-std=c++11") triggers an ICE since
GCC 4.8.0 (when thread_local was introduced):

==============================
thread_local int i = i;
==============================

bug.cc:1:22: internal compiler error: in var_defined_without_dynamic_init, at
