[erlang-patches] Crypto Compile Problem on x86_64 OTP-R11B

[Raimo Niskanen]

It might have been clear, but I did not get it. What is the patch?
Is it to relink crypto_drv.so using gcc 4.0, or is it just to
manually relink crypto_drv.so using gcc 4.1..

If the problem is in gcc 4.1, do you know if it is a 4.1 bug and has
it been reported to gcc - will it be fixed in gcc, or do you know
what is the root cause?

We have suspected the problem being the OpenSSL libraries not
being linked to allow building other (our) shared libraries (.so)
that themselves contain statically linked OpenSSL libraries (libcrypto.a),
but if it is a gcc 4.1 problem we are interested to know for sure.
I might confuse this problem with another problem where we can not
build crypto_drv.so on OpenBSD against libcrypto.a...
