Greetings,
I've ben trying to execute some pattern recognition software that we are
trying to evaluate on different OS/system architectures for an acedemic
client. Although it runs fine on NetBSD, and other unix OSs, on FreeBSD
it dies with a floating point exception for some reason. Annoying :-)
I wonder if this is a problem with not cancelling the relevant bits by
default in the FP exception mask; we had this problem when we ported
NetBSD to the ARM, and although it was 'technically correct' to have the
system throwing a wobbly at everything, in the end we changed it and
disabled some stuff due to it annoying too many people.
Of course that may not be the problem, in which case I apologise the
above paragraph :-)
Regards,
Neil
