The fact that you mention merging with master, and the fact that you're
trapping signals, suggests that you're running a modified Pg. Without
knowing what your changes are, it's probably going to be hard for anyone
to help. Thanks to the joy of C, it's easy to stamp all over the stack
or the heap, so all sorts of weird and wonderful things can happen in
code unrelated to the real source of the problem...
