Hmmm - Great stuff. There is one procedure i know crashes Scid, and
this feature is using it.  It is engine::search. If anyone with engine
programming experience would care to look at it ? Ralph's example
seems a decent way to get it to dump core. Backtrace is below.

Until it is fixed, you can just add this return line to disable it in
the uci game (tcl/tools/analysis.tcl)
.....
proc markExercise { prevscore score } {
+ return
......


Cheers.
