openssl.c

I'm +1 on adding it for several reasons, one of which is there are plenty of 
RHEL 5 (and OL 5) sites out there.

PS the testcase wasn't attached to your email.

It's not worth adding a test for, it's never going to re-occur and it only 
affects 4 year old versions of OpenSSL. Basically RHEL 5 is the only thing with 
a problem.

I wrote one but don't want to add a somewhat useless test. Attached, but the 
extra second to test running isn't worth it.

hi,

do you have a test case for this crash?

Cheers,
