Passing only one parameter to DH constructors is fine; g and p are only
used (and accessed) if group is MODP_CUSTOM, but not for a specific
group (we assume a caller clean-up calling convention).

The crash happens at the function entry point. I can't reproduce this
without your hardware, but I've seen that before. It might be related to
a long call to the OpenSSL library; building with -mlongcall helped in
