The problem seems to be related to the STT_GNU_IFUNC support in glibc.
It's something that has been added in Squeeze, and indeed the problem is
reproducible there.
There might be some way to get it working again, but given there are now
better way to do profiling, even without the need to recompile and using
the normal debugging symbols, I think it's time to just get rid of of
this package. It doesn't seems to be really used anyway [1].
Any thoughts?
