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 {
