Using Multi_key and the key combinations defined in
/usr/X11R6/lib/X11/locale/iso8859-1/Compose is the way to go if you're
in the ISO-8859-1 locale. I wrote about this in another message
yesterday in col.misc; did you see it? Message-ID is
slrncceesd.8nv.danSPANceswitTRAPhcrows@samantha.crow202.dyndns.org .

Can't suggest anything without looking at the code here, but the lowly
printf() can be very helpful in lots of circumstances. Just sprinkle
them everywhere (like breadcrumbs) in the area where you think the bug
is, and look at the last one you get before the crash, then the bug's
between that printf() and the next one. Iterate, and eventually you
find the bug.
