indeed: while gdb works reasonably well on Solaris, I had a couple of
cases (often related to corrupted stacks) where dbx dealt with the issue
way better (or even at all) compared to gdb which could be thrown off-track.

I hope to get a few fixes into gdb for the 8.3 release that would
benefit both Solaris 10 and 11, but after that, I'm done with S10.
