Hm, looks like the vg_intercept stuff isn't working - it's catching
poll, but it isn't passing it into the threads library properly.  What
does ldd <your program> say?  What is in /proc/<pid>/maps when you run
it?  What does the link command line look like?

Did you manage to get a small standalone program to reproduce the
problem?
