This only affects OpenMP-enabled builds here, so it is likely a thread
safety issue, maybe with older OpenSSL on that machine. If the issue is
in fact inside OpenSSL, we'll need to add #if's to disable OpenMP in
ssh_fmt.c if the version of OpenSSL is too old (need to figure out what
problem this is and in what version it got fixed).
