[redland] Segfault w/ example.pl using repat parser

[Chad House]

I get segfaults when attempting to run the example.pl test file
included with redland 0.9.10. "make build-perl" works, and "make
test-perl" passes all tests, however.

Also, if I change the parser (example.pl line 49) from 'repat' to
'raptor', then example.pl runs fine.

Here's the backtrace from the core file, FWIW:

'rpm -qf /usr/lib/libxmlparse.so.0' tells me the library belongs to the
w3c-libwww package. I had version 5.2.8 installed (stock Red Hat 7.1),
but upgrading to 5.3.2 fixed the problem.

I'm using perl 5.6.0, configuration below.

Regards,

Chad
