            Bug ID: 67398
           Summary: Segfault when template static references another
                    template
           Product: gcc
           Version: 5.2.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: jeanmichael.celerier at gmail dot com
  Target Milestone: ---

Error given by gcc : 
/home/jcelerier/i-score/base/plugins/iscore-plugin-scenario/source/Process/ScenarioModel.cpp
: dans l'instantiation de ‘const qt_meta_stringdata_NotifyingMap_t
staticStringData<ConstraintModel>’ :
/home/jcelerier/i-score/base/plugins/iscore-plugin-scenario/source/Process/ScenarioModel.cpp:57:29:
  required from ‘const QMetaObject
NotifyingMap<ConstraintModel>::staticMetaObject’

  required from here
/home/jcelerier/i-score/base/plugins/iscore-plugin-scenario/source/Process/ScenarioModel.cpp:31:3:

 } staticStringData{};
   ^

Rough translation of the last line : Internal Compiler Error : segmentation
fault.

The relevant part starts at line 196141 of the attached preprocessed source.
It started when I added a template at line 196240 :

      staticStringData<T>.data, 

The "required from here" refers to an usage of staticMetaObject in code.


Requires -fPIC and -std=c++14.
