[gnugo-devel] Access violation in 3.3.18 compiled with Visual C

[Teun Burgers]

I can confirm this for the mingw versions. The cygwin version gives
S7 as move.

Attached are two backtraces.
mingw-g.txt: -g compiled
mingw-gO2.txt: -g -O2 compiled.

This is the -g -O2 message:

This GDB was configured as "i686-pc-cygwin"...
