Holger posted a game which he reports crashes which is in the bearoff
stage on one side - gnubg is bearing off, holger has just come in from
the bar. I think the other posted crashing match was also bearing off
on at least one side.

I'm very curious if br1.c on Windows has the complete database. If the
Windows environment has a grep which supports the -n option, then it
would be interesting to do:

address@hidden:/home/jes/gnubg% grep -n '[{}]' br1.c
31:static unsigned char acBearoff1[] = { 
183256:};
183260:BearoffInitBuiltin ( void ) {
183264:  if ( ! ( pbc = (bearoffcontext *) malloc ( sizeof (
bearoffcontext ) ) ) ) {
183268:  }
183286:}

This tells me that the bearoff database starts on line 31 of the file
and ends on line 183256. Could Nardy or Holger try this and see if the
array is the same size - the difference between the line numbers for
the open and close braces should be the same. I'm just very puzzled by
the reported odd behaviour when building br1.c and I'd like to be sure
that the full database is present.
