We are having the same problem with several Zenith 248's (12 Mhz 80286 +
8 Mhz 80287).  They are ok with Turbo C and Turbo Basic, but QuickBasic 4.5,
MS-Fortran (Old - V. 2.5 or something) and WATFOR Fortran will crash as above.
 
The programs in QuickBasic *seem* to get into the 87-exceptions routine, but
since the crash wipes out the debugger, it's hard to be sure.
 
Any suggestions?
