FreeBSD clears the exception register in the fpu when the trap code catches an fpu exception prior to calling the user's handler, if any. In npx.c, the exception register is cleared prior to sending a SIGFPE to the process. I want to be able to catch an exception, if I want, and determine what the cause of the problem was, and, possibly work around it. I want my exception handler to know exactly what the exception was. tomdean
