           Summary: PCRE library segfaults on random input

test file

In using PCRE library, I wrote a test that feeds random input to the library
both for expressions and match strings. Some random expressions seem to cause
segfaults. I've included one of the strings that caused segfaults for me in
the attached test program. Note that in my intended use of the library, the
expression strings will be user inputted and it is important that the PCRE
library be tolerant of arbitrary input. Pls let me know if you need any
further information.

regards, Mark
