I cannot seem to reproduce your issue on my end using openssl-1.0.1e compiled from scratch.

I've modified the build script to download a specific version of openssl, build it, and link when building mcps.
This modification is not yet in the master branch, but you can get it from https://github.com/hdznrrd/mircryption-xchat2/tree/hdz/custom-openssl or as a handy .zip file right here https://github.com/hdznrrd/mircryption-xchat2/archive/hdz/custom-openssl.zip

Can you please then run the build script as follows:

This should download openssl 1.0.1e, the same version you're using already, build it and link against the just built version.
Please let me know if this behaves any differently from your previous test.

hi qiutet,
did you use the version from my github repo?
https://github.com/hdznrrd/mircryption-xchat2

if not, please try this one first and see if the issue persists.
if it does i can take a look at it :)
