Public bug reported:
FPU bug in qemu-system-i386 makes software which use floating point
numbers work incorrectly. For instance, the one included in attachment
prints out 0 instead of 2147483648. The same code works ok in qemu-
system-x86_64.
I have this issue in QEMU 2.3.0 on two different x86 guests (Parabola
GNU/Linux-libre and libreCMC).
** Affects: qemu
Importance: Undecided
