v22.1a16

Regexp() can still crash apparently.  When using my grep command, if I=20
do something like grep blah * in my source directory that has my mudos=20
binary files (the driver compiled files, not the lpc binaries), the=20
driver will crash:

[an object in the array?  More likely an unitialized svalue ...]

Don't know how helpful that is.  If there's anything you can think of=20
that I can do to narrow this down to something more specific, let me=20
know.
