This is with openssl 0.9.6b, openssh 3.0.2p1, and Mac OS X 10.1.1

Please send a full debugger trace.

Do you have any old OpenSSL headers lying around?
Comment 2 Robert Harder 2001-12-14 03:10:25 AEDT 
In response to the question "Do you have any old OpenSSL headers lying around?":

No. Strangely, Mac OS X 10.1 doesn't come with the openssl headers - only a 
compiled binary. The openssl headers that I _do_ have are the ones that I 
compiled and installed from the 0.9.6b non-engine version of openssl.
