both of these are probably caused by the new regex library, which is
taken from current glibc (GNU libc) cvs tree.

The slowdown has to be viewed as necessary price for full support
of POSIX regular expressions.  There is probably space for performance
improvement, but going back is no option.

The coredump should be, IMHO, fixed before the release is made.

The first step is to try whether the bug has not been fixed yet.
Could you please test it?  You need to replace the reg* files by those
from current glibc CVS.

Could you please try the following patch:

http://www.math.cas.cz/~kasal/sw/gnu/gawk/gawk-3.1.1l-cvs_regex.patch.bz2

(also available as
http://www.math.cas.cz/~kasal/sw/gnu/gawk/gawk-3.1.1l-cvs_regex.patch.gz )

(Or check the CVS accessible from http://sources.redhat.com/glibc,
subdirectory posix/, files reg* (except regexbug1.c) yourself.
The patch is up to date, at the time of writing this mail.)

Does it fix your problem?

Regards,
