Hi, looks like Debian's gcc-4.0 4.0.1-6 generates bad code with -O2 on
parisc:

The same problem may apply to the arm architecture, I cannot check right
now, there's no Debian arm developer machine available.

Hi, I re-checked on paer with

 $ gcc -v
 Using built-in specs.

 Thread model: posix
 gcc version 4.0.3 20060128 (prerelease) (Debian 4.0.2-8)

it builds (and selftests) fine again with -O2.
