Comment(by midnightmagic):

 SUCCESS! Rebuilding pycryptopp without ASM optimizations makes it pass the
 chunked SHA256 test, and setting PYTHONPATH to that top-level directory
 makes "tahoe ls" Just Work on an existing grid, and the failing command
 NOW WORKS PERFECTLY.

 So there is a patch in pycryptopp/ticket/24 for setup.py which detects the
 platform involved and turns off assembly optimizations in just that
 specific platform and bit-width (32bit).

 I would say that, if bdew could do the same and it works, we can put a
 platform detection for his also and likely close all these tickets out
 until crypto++ fixes their CPU features detection.
