Can you still reproduce this problem with the latest version of QEMU? As
far as I know, the FPU emulation has been completely switched to
softfloat with the latest versions, so I assume your problem might be
fixed in recent releases...

Title:
Python 3.1.2 math errors with Qemu 0.12.5
Status in QEMU:
Incomplete
Bug description:
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:
