[Pkg-openmpi-maintainers] Bug#531522: RFH: error in dlopen?

Hi everyone,

I'm trying to find the reason for bug #531522. The Open MPI compiler
wrapper of Open MPI 1.3.2 segfaults when called with fakeroot. I have
the feeling that eglibc's dlopen()/dlsym() might be the problem but I'm
not sure enough to file a bug report. It would be great if someone could
have a look at it and enlighten me. It's blocking the Open MPI
transition and I'm kinda lost at the moment.

As far as I can say, the problem does not appear on a Lenny system with
Open MPI 1.3.2. Before the transition started, I rebuilt all packages
that depend on Open MPI in a sid chroot which worked fine. This was
before the switch to eglibc. This is why I think it might be eglibc
related, and not a problem in Open MPI itself.

I've not found a list of differences between glibc and eglibc that shed
some light into that, so this is why I ask you, the experts. If I can
provide any further information besides the backtraces in the bug log,
please feel free to ask!

Thanks in advance!

Best regards
Manuel
