[gnugo-devel] cvs of 12-10-2004: mkpat crash for mingw version

[a.rburgers]

mingw mkpat.exe crashes when generating owl_attackpat.c.
The command line is the following:

run -D -m -b -t ../../patterns/owl_attackpats.dtr owl_attackpat -i 
../../patterns/owl_attackpats.db -o owl_attackpat.c

When I apply the patch at the end of this message, the following
is printed:

member_att: att is -1414812757.
Program exited with code 01

The cygwin version does not suffer from this problem.
I wonder if this might have anything to do with
the ChangeLog entry "- DFA micro optimization". Up to quite
recently it build without problems.
