I do not see this in my current sagemath-5.4 rpm package, but I suspect it
may have been either corrected or worked around by one of the patches at
http://pkgs.fedoraproject.org/cgit/Singular.git/tree most likely
`Singular-undefined.patch`, but the padding added by `Singular-
M2_memutil_debuggging.patch` may be actually hiding some problem. Or, it
may be something different, the singular rpm was known to not build
properly or generate proper binaries if an older singular was installed
but I did not care much about that because official rpms are built in a
''clean'' chroot.
