Did experience this on the combination Windows/gcl. Now I did experience the same thing on the combination Linux/sbcl: If I start wxMaxima from a terminal and then interrupt it using Ctrl+C one CPU is running constantly thereafter. On my linux/sbcl version I get an endless stream of the following console output in this case:

   Help! 11 nested errors. SB-KERNEL:*MAXIMUM-ERROR-DEPTH* exceeded.
   Backtrace for: #<SB-THREAD:THREAD "main thread" RUNNING {1006CCED13}>
   Help! 11 nested errors. SB-KERNEL:*MAXIMUM-ERROR-DEPTH* exceeded.
   Backtrace for: #<SB-THREAD:THREAD "main thread" RUNNING {1006CCED13}>
   Help! 11 nested errors. SB-KERNEL:*MAXIMUM-ERROR-DEPTH* exceeded.
   Backtrace for: #<SB-THREAD:THREAD "main thread" RUNNING {1006CCED13}>

There seems to be no really portable way to catch a SIGSEV or similar, though.
