--- Comment #2 from Matt Ball <matthew.ball@xxxxxxx>  2009-08-11 07:51:53 PDT ---
I found another core file in the ~/.wireshark directory.  This might be the
correct one:

(It looks like the coredump may have been from a call to strlen (via vfprintf)
from within ssl_debug_printf).  

Maybe the SSL debug code is trying to print out a bogus value that the Solaris
vfprintf function can't handle?
