I was working to implement your proposed solution - it seemed most logical
to place overlay_prev_vec in the buffer struct, but placing the three
necessary properties( overlay_prev_vec, noverlays_prev,
prev_point_motion_hook ) in the structure caused the 'make' process to
return a segfault. I'm going to look into this more in a few days, but do
you have any idea why this would be happening, or another implementation
strategy that wouldn't run into this problem? I followed the instructions
about placing non-Lisp_Objects above the 'name' variable, so that is most
likely not the issue.
The last few lines produced by running make were:
LC_ALL=C `/bin/pwd`/temacs -batch -l loadup dump
Segmentation fault
make: *** [emacs] Error 139
Thanks,
Nathaniel Flath
