Alexandre,

I was wondering if you have looked at PR 28672?  It looks like it was
triggered by this checkin though I don't know if it was a latent bug or
a problem with your change.  I have looked at it a little since it is
blocking the IA64 Linux bootstrap but I have not been able to figure out
what is going on.  The main loop in vt_find_locations does not appear to
ever end because "fibheap_empty (pending)" is never true.  I am not sure
why this is and am not very familiar with this part of GCC.
