Hmmm, if perfly town.perfly runs fine and you're getting that stack
trace with your app, you may have found a bug. Do me a favor and:

setenv LD_LIBRARY_PATH /usr/lib/Performer/Debug
run your app
gdb app core
(gdb) where

you should have the same stack trace but with line numbers.
send that to mongoose-feedback++at++corp.sgi.com and we'll take a closer look
at things. it'll help if you have a small app that reproduces the problem
that we can run here.

thanks,
tom
