[Libmesh-devel] Bug in NemesisIO?

[Roy S. <roy...@ic...>]

If I switch ex14's output format from ExodusII to Nemesis, and if I
set output_intermediate=true in ex14.in, and if I run on 4 processors,
then I get a crash at the first output step.

METHOD=dbg shows me *where* the out-of-bounds vector access is, but I
don't know the Nemesis_IO_Helper code well enough to figure out what's
going wrong.  Based on the failure conditions I'd assume it's another
code-doesn't-work-with-more-processors-than-coarse-elements bug, but
since there are some if cases in the Nemesis which specifically try to
test for such bugs, maybe it's something more complex.

Anyway, I'm not going to have time to look into it more deeply myself
soon, so I figured I'd throw it out to the list in case anyone more
familiar with the Exodus/Nemesis code wants to see if it's replicable
and/or fixable.
