Bug ID: 67354
Summary: internal compiler error: in add_to_same_comdat_group,
at symtab.c:421
Product: gcc
Version: 5.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: bgreen0 at gmail dot com
Target Milestone: ---
Created attachment 36255
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=36255&action=edit
preprocessor output
The attached preprocessed code generates an internal compiler error when
compiled with the -Os option. Tested with g++ 5.1 and 5.2.
Preprocessed file attached.
Here is the command line out output:
$ g++ -v -save-temps -std=gnu++11 -Wall -Wextra -Os -c -o gccbug.o gccbug.cpp
Using built-in specs.
