One interrupt vector is assigned to take care of all floating point exceptions (location 0244). The seven possible errors are coded in the four bit FEC (Floating Exception Code) register as follows:

2 Floating Op code error 4 Floating divide by zero 6 Floating (or double) to integer conversion error 8 Floating overflow 12 Floating undefined variable 14 Maintenance trap

You can find this value by running PFE (I). Also, using ADB on your core dump might prove helpful.

Perhaps UNIX-WIZARDS is not the right place to send questions like this? -Mike
