^X-^B appears to lose when I have done Select System as Tags Table and follwed by Tags Search

[Leigh L. Klotz <KLOTZ@OZ.AI.MIT.EDU>]

In Symbolics 3640 Release 6.1, IP-TCP 29.13, Experimental New-Boxer 5.0,
microcode TMC5-IO4-ST506-MIC 336, on Lisp Machine Rocky Graziano:

the string.  From then on ^X-^B died in this manner.  "Eval" was the
name of the system.

>>Trap: The first argument given to the SYS:FAST-ASET instruction, #\E, was not a fixnum.
