Found a segmentation fault on windows system with OpenSSL-1.0.1-t. After rollback to OpenSSL-1.0.1-L everything is works fine.
Issue could be reproduced with the following code:
perl -MCrypt::SSLeay::CTX -e 'Crypt::SSLeay::CTX->new(2);"
We found it when we tried to http get via LWP::UserAgent our old server, which has SSLv2.0 only. Our perl is 5.8.9.
