Selinux issues in user-compiled code

[Jason L Tibbitts III <tibbs math uh edu>]

A while back I made the decision to enable selinux on all of my user
desktops.  It hasn't really been all that painful; generally the
issues I have are with proprietary software, essentially all of which
it seems has one issue or another.

This morning I received the following question from a user:

-----
Can you explain why I often get a linker  error:

"cannot restore segment prot after reloc: Permission denied"

running code I've built in my home directory.But then if I rerun once
or twice it will execute properly.  It's not always the same library
that the linker complains about....
-----

Unfortunately I don't really know how to answer.  I can handle selinux
at a system level, because if I know some program has an issue I can
just change a file context and things work.  But I've no idea how to
deal with code that users might compile, or where to point them for
info in writing code that doesn't have these issues.
