Re: Using changeword in M4-1.4.1 can cause Segmentation Fault

Hi Frank,

Sorry for the delay, I have been busy with Libtool (and moving house!).

Thanks for the report, I've fixed the bug by compiling the regex to a
temporary buffer without overwriting current word_regex. to flush out any
errors in the regex before doing a real compilation to word_regexp only
if the dummy compile succeeds.

I may release 1.4.3 this weekend if my new internet provider connects
me, and I can clear the patch queue.

Cheers,
        Gary.
