Yep! This was ultimately what the problem was - a missing cleanup of the
context after the config stage. Not a problem for straight forward certs
without an engine, but posed a problem in CHIL. Thank you for pointing
this out.

I'm still scratching my head about why the error manifested as a
segfault on Solaris SPARC and as CHIL (validly) complaining/bombing out
on AIX and RHEL. Unfortunately, it seems my debugger gets in the way
when trying to figure this out, so it may be a mystery to me forever.
