Advice on diagnosing segfaults?

Hi,
I've got a segfault in one of the language bindings I'm developing
(fontconfig-pure), and I'm struggling to locate it.
I see it occur in another project calling the language binding (so
unfortunately I don't know what exactly is causing it), but GDB tells me
that it occurs within a particular function I'm language binding to (and
nothing more). I've attempted a few theoretical fixes without
improvement (beyond triggering an infinite loop instead). And setting a
breakpoint on the wrapper-function I added to create a better ABI to
language bind to shows that dozens (if not more) of these calls
successfully before I hit the segfault.
I'm not sure how to diagnose this issue, any help would be appreciated!
Cheers,
Adrian Cochrane
