make one connection with isql, do nothing in it, then start fbtracemgs and ctrl+c it until you get segmentation fault:

Paulius, I could not reproduce segfault.
Can you provide stack traces for all threads, not only for one in which segfault happened?

Same might happen with fbsvcmgr.
Does not need frontporting - in FB3 there are no reasons for this segfault.
