Bug ID: 60146
Summary: Regression: ICE when compiling this code with -fopenmp
Product: gcc
Version: 4.8.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: tweenk.pl at gmail dot com
The linked preprocessed code compiled correctly in GCC 4.7.x (Ubuntu 13.04).
After upgrade to GCC 4.8.1 (Ubuntu 13.10), it crashes.
The code is too big (3.1MB) to attach it to the bug report and cannot be easily
reduced, so I'm providing a download link:
http://osch.chem.uw.edu.pl/gccbug.cpp
Compile with: g++ -fopenmp gccbug.cpp -c -o gccbug.o
