I'm afraid I don't know all the intricacies of delaing with segfaults, but I can ask some questions that would assist the developers. Based on the question, I assume you're using linux. I also assume that the crash is reproducable.

What window manager are you using?
What version exactly are you using? is it the 1.14.0-beta2 source or the CVS-HEAD source?
Do you have the core file and can you generate a backtrace?

Please start the freeciv client with gdb, for example in this way

gdb client/civclient

(or replace client/civclient with whatever path you have to civclient) then type "run". When it segfaults, type "bt" and post the results. Also run "civclient -d 3" and post the output from that.

I am also getting a Segmentation fault. I compiled Freeciv 1.14.0 under X11 (0.1, XFree86 4.2.1) on Mac OS X 10.2.3.

The segfault only happens when I try to build a city. So long as I just move my units around, things seem to be fine.
