 Replying to [comment:1 neteler]:
 > I have tried to reproduce it with your scripts but no issue here (Fedora
 21, 64bit).


 My platform is x86_64 CentOS release 6.6.

 Beware that to reproduce, you have to be in a long enough path.  For
 example in
 {{{
 /home/dumas/tmp/AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA/grass_bug_d_vect_segfault
 }}}

 > In your report there are "<value optimized out>", can you please
 recompile after "make distclean" without compiler optimization in order to
 obtain a better debugger report?

 Here it is (recompiled with -O0):
