Thi sis definitely one cause of the problem. Another one might be
optimization for a incorrect cache line size (32 instead of 16
bytes).

This has never been working reliably for any real-life code. And it's
awfully slow.
Also note that you CANNOT mix standard binaries (from Debian) and 8xx
specific libraries (from ELDK) - this will crash as soon as an
application attempts to use floating point.
