I applied this patch, build with the config-switches you have suggested.
Running it (not thru gdb this time...) gave:

 yotamm@huby:emacs:549> /usr/local/bin/emacs

 xdisp.c:22676: Emacs fatal error: assertion failed: s->font
 Fatal error (6)Aborted

I understand that Chong suggested some test steps.
Please resolve exactly what you would like me to try.
I would love to help, but my time with this environment
(where home-built emacs fails) is limited.

regards -- yotam
