NWFPE: ... takes exception ?

Subject: NWFPE: ... takes exception ?

Hi there,

I build an application woth arm-softfloat-linux-gnu compiler.
After that application stopped working I just noticed loads of

NWFPE: hrdisplay[43] takes exception 00000002 at c002b1b0 from 0004f8a4

in my kernel log.

I guess NWFPE is the kernel floating point emulator.

But:
a) what means "exception 00000002"
b) I use a softfloat glibc. So why is the NWFPE used anyway?
   Could it be a division by zero?
   But this should be handled in softfloat glibc.

I am using gcc-3.3.3-glibc-2.3.2-linux-2.6.8 from crosstool-0.28-rc37.

Thanks!
