Hi. Here is a patch for a bug that I just (re-)fixed in gawk.
It looks like there has not been much activity in the CVS in a long
while. Sigh.
In any case, valgrind is your friend; this showed up in gawk in a UTF-8
locale.
In general, it is worth comparing the gawk dfa.c with the grep one; I
have fixed a few bugs there.

* src/dfa.c (parse_bracket_exp_mb): Don't set work_mbc->chars
to NULL to not leak the memory allocated a few lines earlier.
