            Bug ID: 67935
           Summary: internal compiler error: Segmentation fault
           Product: gcc
           Version: 5.2.0
            Status: UNCONFIRMED
          Severity: critical
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: niqingliang2003 at gmail dot com
  Target Milestone: ---

Created attachment 36484
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=36484&action=edit
compiled with command: g++ -std=c++11 main.cpp

main.cpp is the smallest code for generating the compiling error.
compile command: g++ -std=c++11 main.cpp
platform: archlinux
gcc version: 5.2

error info:
internal compiler error: Segmentation fault
  void serialize(_T & o)

workaround 1:
change 'typedef struct { ... } base_t' to 'typedef struct xxx {...} base_t'

workaround 2:
move the '#include <array>' in the first line.


when change the 'array' to 'vector' (both header and declaration of 'p' in
base_t), result become:

internal compiler error: Segmentation fault
 typedef struct {
                ^
