Mikmod's OSS driver contains an allocation bug,
which happens to be hidden most of the time
with OSS/Free (although it can be triggered by
environment variables), but gets triggered
by some non-OSS/Free sound drivers.

On a side note, mikmod 3.0.4 seems to fix some
problems with certain mod files...
This bug has been fixed for future releases.
It will be available from Rawhide at ftp://rawhide.redhat.com
