[gnugo-devel] DFA bug

[Teun Burgers]

The following shows there is something going wrong
with malloc when building DFA's. On linux
MALLOC_CHECK_ makes malloc a bit more verbose:

setenv MALLOC_CHECK_ 1

./mkpat -D -m -b o -i owl_defendpats.db -o zz.c
malloc: using debugging hooks
malloc: top chunk is corrupt
Segmentation fault (core dumped)

Either we are overwriting something or there
is a bug in glibc's malloc
