Public bug reported:

When doing the regression tests for Python 3.1.2 with Qemu 0.12.5, (Linux version 2.6.26-2-686 (Debian 2.6.26-25lenny1)),
gcc (Debian 4.3.2-1.1) 4.3.2, Python compiled from sources within qemu,
3 math tests fail, apparently because the floating point unit is buggy. Qmeu was compiled from original sources
on Debian Lenny with kernel  2.6.34.6 from kernel.org, gcc  (Debian 4.3.2-1.1) 4.3. 

Regression testing errors:

test_cmath
test test_cmath failed -- Traceback (most recent call last):
  File "/root/tools/python3/Python-3.1.2/Lib/test/test_cmath.py", line 364, in
