I can trigger the bug using Chicken 3.4.7 when compiled with the
supplied regex.scm file (again I can do this by varying the -:s
parameter until it gets stuck).

A backtrace from GCC is attached (it continues to repeat through many
frames after the output given).  It exhibits behaviour similar to that
when using the regex.scm that comes with Chicken 3.4.7 normally.  The
regex.c file which is generated is on my website at:

    http://real.metasyntax.net:2357/tmp/regex-pcre.c.gz

(Probably just my ignorance talking here again, but even though the
header on the file says PCRE, there are a lot of references to irregex
scattered throughout that file.)

Thanks for the continued time to try to solve this,
