That was close, the latest released curl version is 7.17.1 :)

Anyway...

$ grep -n -C3 "couldn't create a context\!" lib/*.c
lib/ssluse.c-1295- connssl->ctx = SSL_CTX_new(req_method);
lib/ssluse.c-1296-
lib/ssluse.c-1297- if(!connssl->ctx) {
lib/ssluse.c:1298: failf(data, "SSL: couldn't create a context!");
lib/ssluse.c-1299- return CURLE_OUT_OF_MEMORY;
lib/ssluse.c-1300- }
lib/ssluse.c-1301-

IOW openSSL's SSL_CTX_new() failed, libcurl interprets this as an out of
memory condition, which may or may not be true (I've never programmed
with openSSL, so I don't know and can't provide a patch right now).

But the problem you're seeing is caused by openSSL. Download the latest
libcurl source, improve the error message in libcurl's ssluse.c to see
what's openSSL really complaining about, fix the issue with openSSL and
post the ssluse.c patch here if you find out that SSL_CTX_new() can
really fail due to other than memory reasons ;)
