The above situation seems to occur during nested exceptions. I tested a standalone illegal instruction exception, and it worked fine.

The mepc matches.

Difftest does not sync registers upon exceptions. What it does it to compare the states of REF with the states of DUT. mepc of Spike is never affected by the DUT.

From your logs, Spike raises an illegal instruction exception on 0x00000000800020bc with mtval of zero. Please check your workloads and Spike logs to see why Spike sees this.
