pgcrypto related backend crash on solaris 10/x86_64

I brought back clownfish(still a bit dubious about the unexplained
failures which seem vmware emulation bugs but this one seems to be
easily reproduceable) onto the buildfarm and enabled --with-openssl
after the the recent openssl/pgcrypto related fixes but I'm still
getting a backend crash during the pgcrypto regression tests:

http://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=clownfish&dt=2007-09-09%2012:14:50

backtrace looks like:

program terminated by signal SEGV (no mapping at the fault address)
0xfffffd7fff241b61: AES_encrypt+0x0241: xorq (%r15,%rdx,8),%rbx
(dbx) where
