Hi,

I'm experiencing odd behaviour which results in a bus error & core dump on 
Solaris. I'm using OpenSSL as the SSL provider for stunnel 4.05.

I can successfully start stunnel to open a tunnel to one host, eg:

accept=localhost:4445
connect=host.domain.com:14445

but I get a bus error & core dump in OpenSSL on starting stunnel when I try and 
open a tunnel to a different host, eg:

accept=localhost:4445
connect=hostUAT.domain.com:14445

Backtrace as follows:

(gdb) where
#0  0x000b83e8 in engine_table_select ()
#1  0x0006e514 in RAND_status ()
#2  0x00030770 in prng_seeded (bytes=0) at ssl.c:284
#3  0x00030678 in init_prng () at ssl.c:182
#4  0x00030378 in context_init () at ssl.c:79
#5  0x0003185c in main_execute () at stunnel.c:102
#6  0x00031780 in main (argc=0, argv=0xffbef684) at stunnel.c:72

Environment is OpenSSL 0.9.7b from Stunnel 4.05 on Solaris 8.

What might cause a host name change to result in a bus error from the random 
number generator code?

Regards,

Andrew Gubb
