--- Comment #12 from Dilawar Singh <dilawar.s.rajput at gmail dot com> --- (In reply to Marc Glisse from comment #10) > Looks like a dup of PR 48891. Yes. It is very similar to this. Fine with me if it is marked dup. I was mistaken about gcc version on server. It is default gcc comes with Ubuntu-Precice (gcc-4.6.3). Also -std=c++0x flag is not set with gcc-4.6.3. So in nutshell, compiles with gcc4.6.3 without -std=c++0x, but fails with gcc-4.8.0 with -std=c++0x. I mentioned -std=c++11 wrongly in first report.
