Hi Rick,
Can you run the truss(1) command when you run "openssl version" as follows?
i.e.
% truss -lf -u libcrypto:: -u libpkcs11:: -o /tmp/truss.out openssl version
The output will tell you more information about the function calls made
by the openssl(1) application.
Thank you,

Request: Bug Report
Hello,
I recently compiled OpenSSL 1.0.2(c,d) for Solaris 5.10 using GCC 4.8.2 on an UltraSPARC
45 and our group tested it on several different types of other systems (V245, T4, T3,
etc...) and it runs as expected on all systems except the T3 where it hangs - even for a
simple call like "openssl version". The process continues normally when sent
either a SIGBUS or SIGILL.
I believe I've tracked it down to the function "OPENSSL_cpuid_setup" in the file
"crypto/sparcv9cap.c" after the initial sigaction calls to set the signal handlers for
SIGILL and SIGBUS and before the trailing sigaction calls to reset the handlers for SIGILL and
SIGBUS. There's a partial dtrace listing below, generated by my colleague Carolyn, with the last
output lines showing the sigaction calls for SIGILL then SIGBUS (the trailing sigaction calls are
in the reverse order in the code).
The "OPENSSL_cpuid_setup" function supports reading the environment variable
"OPENSSL_sparcv9cap" to skip further processing and setting this variable (to anything)
prevents the process from hanging, so I'm also encouraged that the issue resides within this
function, but am, obviously, hesitant to rely on this as an operational solution ...
Is there any other information I can provide you and/or anything I can do on my
side to investigate and resolve this.
Thank you,
- Rick
