Are you certain that the message is related to the death of the process?
This message is a warning to let you know that your application has run into
one of the corner cases of IEEE floating point that is not implemented in
hardware by the processor (typically operations involving denormalized numbers
will cause this, but there may be other cases). There is rate limiting code in
the kernel to prevent this message from flooding the logs (and from becoming
even more of a performance drag than taking a trap and emulating in s/w).
It is relatively normal to see this message (even multiple times from the
same process), and it usually isn't fatal.
