llvm dev - Aug 2010 - [LLVMdev] possible miscompilation of openssl on x86-64

Hi folks,

I'm playing with this version of OpenSSL:

   openssl-SNAP-20100804

On x86 using clang I can build it and run all tests successfully.  On 
x86-64 using clang r110287 I get the error message below during "make
test".

Not sure if anyone has time to look into this but I'm probably not the 
right person to start debugging it...

Thanks,

John Regehr

John,

I actually just observed this failure a few days ago, and tracking it down is
fairly high on my priority list.
