The bug 
Compaq referred to was in the FPU on the 486.  It occurs only under very
specific and rare conditions.  Intel says only that a customer found it,
and won't identify which one; Compaq says it was them.  An indication of
how obscure the bus is is that the 486 passes all of Intel's test suites
for the 387.

Intel says that they have engineered the fix, and will have corrected
parts by the end of November.
