See the thread beginning > http://lists.freebsd.org/pipermail/freebsd-stable/2007-November/037947.html Thanks for the pointer into the -stable mailing list. The incorrect precision control bits is a serious quality of life issue for those of us who care about consistent numerical computations and the backward compatibility of our FreeBSD object code. Is there an active community of users who care about numerics on FreeBSD? At any rate, I searched the PR database for a bug related to the incorrect control word setting but came up empty handed. If nothing has been filed to date I will go ahead and submit a PR.
