Sounds like a problem with getting (corect) unwind info for the
signal-frame.  Can you try with a 2.6-based kernel?  (Or is this SLES
9.1---I can never keep the numbers straight...).

For debugging this type of problems, you're generally better off
building with "./configure --enable-debug" and then look at the output
you get with UNW_DEBUG_LEVEL set to, say, 16.
