            Bug ID: 63531
           Summary: gcc segfaults on some sourcefiles when using
                    '-Weffc++' and '-fsanitize=undefined' together
           Product: gcc
           Version: 4.9.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: allizgubccg at reallysoft dot de

gcc version: can reproduce segfault with gcc 4.9.0 and 4.9.1.
System: ubuntu 


Only happens when using '-Weffc++' and '-fsanitize=undefined' together,
removing any of them removes the problem.

Does only crash for 3 out of several hundred source files (all build with
similar switches).

command line: /opt/gcc-4.9.1/bin/g++ -v -save-temps -DDEBUG -DARB_MOTIF
-Weffc++ -fsanitize=undefined -std=gnu++11 -c MG_preserves.cxx -I.

Actually, I can't reproduce it with 4.9 nor with 5.  I'd say your version
doesn't have r215459 yet, which I believe is the fix.  Can you try newer GCC?

I've tried it with 4.9.1 release version.. i don't see any newer release. Which
version should i test?

I meant a GCC build, that contains r215459 fix (for that you'd have to build
gcc, 5 nor 4.9.2 haven't been released yet).

But I'm pretty sure this is already fixed.
