Just FYI.  "Alignment trap" is not usually a hardware issue.  It
is virtually always a software error (specifically, accessing a
16, 32, 64, 80 or 128 bit value through an insufficiently aligned

A stack trace is needed to determine if this is a kernel or user
mode issue, and if so where.

Of cause there is the remote possibility that a hardware error
caused a pointer to have a value it shouldn't have according to
the code.

However unless the error is actually in OpenSSL code, there is
little that this list can do to fix the problem.

Given the specific text of the other error message, I hope you
are not somehow running OpenSSL itself as process 1 (init), as
that would be highly unusual.
