There was/is definitely a problem in OpenSSL compiled with ASM that  
manifested in PHP and, to my knowledge, nowhere else. As I posted  
earlier, my symptoms were different, but the cure was the same.

It would be prudent to try building openssl without ASM and see if  
that solves the problem. Certainly it would take less time than the  
current age of this thread.
