Can you please try putting a breakpoint on sha1_block_data_order_ssse3,

Breakpoint 5, sha1_block_data_order_ssse3 () at sha1-x86_64.s:1295
1295 pushq %rbx
Current language: auto; currently asm
(gdb) p $rsp

[looks ok]
Actually, it doesn'ton function entry, %rsp must be congruent 8 modulo
16. Could you do the same thing (breakpoint and look at %rsp) for the
callers up the call stack?
Do you link dynamically or statically? What's your GCC version?
