Hi Folks I have been working on a threaded ftp client and am able to reproduceably cause an assertion failure within openssl. I am able to trigger it on both my 4.6.2-p13 and 4.8 machines. Looking into it deeper its being cause by openssl not being compiled with the -DOPENSSL_THREADS (0.9.7a) or -DPTHREAD (0.9.6i) CFLAG. Is there any reason we dont have this particular define added in src/secure/lib/libcrypto/Makefile.inc? This file hasnt been touched since 2001/07/04 according to the cvs tag. It would seem other CFLAGs maybe missing as well, if you compare a freshly download and ./configured openssl. thanks Jim
