How reproducible:

I'm not sure whether it's possible to attach 15M archive here, so here is an external link: http://78.153.153.8/tmp/gccbug.tar.xz

Steps to Reproduce:

1. Download the tarball.
2. Extract with 'tar xvJf gccbug.tar.xz' and go to 'gccbug' directory.
3. Run './run' shell script
  
Actual results:
