[Mono-dev] DeflateStream : bit length overflow

[Wade Berrier]

I looked at the build logs, and DEBUG is not defined anywhere.  (I also checked config.h)

Here's the exact make output for trees.c:

if /bin/sh ../libtool --tag=CC --mode=compile /usr/bin/gcc -DHAVE_CONFIG_H -I. -I. -I.. -pthread -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include   -I..  -DGC_LINUX_THREADS -D_GNU_SOURCE -D_REENTRANT -DUSE_MMAP -DUSE_MUNMAP -D_FILE_OFFSET_BITS=64  -O2 -march=i586 -mcpu=i686 -fno-strict-aliasing -g -Wall -Wunused -Wmissing-prototypes -Wmissing-declarations -Wstrict-prototypes  -Wmissing-prototypes -Wnested-externs -Wpointer-arith -Wno-cast-qual -Wcast-align -Wwrite-strings -MT trees.lo -MD -MP -MF ".deps/trees.Tpo" -c -o trees.lo trees.c; \
then mv -f ".deps/trees.Tpo" ".deps/trees.Plo"; else rm -f ".deps/trees.Tpo"; exit 1; fi

Not sure what's going on.

Do you have a code snippet I could try out?
