Octave dies and segfaults on execution of any nontrivial code iff compiled with +hdf5. Compiled -hdf5, octave runs fine. Reproducible: Always Steps to Reproduce: 1. USE="hdf5" emerge octave 2. B0rked. 3. USE="-hdf5" emerge octave 4. Works. 5. USE="hdf5" emerge octave 6. B0rked again.

Created attachment 113401 [details] core dump from octave This core dump is probably of no use.
Created attachment 113403 [details] Stack trace This stack strace (from strace) shows octave's response to 'sqrt(2)' in interactive mode. Only the last 50 lines or so are likely to be relevant.
I forgot to mention the version: sci-mathematics/octave-2.1.73
Recompiling octave-forge after changing octave's useflags fixes the problem. I wish portage knew enough to automatically recompile octave-forge in this case.

I guess the best we could do would be to add a comment in octave's pkg_postinst(). I'll see if I can reproduce this issue on my dev boxes and will add a warning if it is reproducible. Thanks, Markus
