[dsc] dsc malloc() memory corruption error

[Ted Fines]

Hi,

Thank you.  Still having problems, unfortunately.

The source download at
http://dns.measurement-factory.com/tools/dsc/download/dsc-200911111630.tar.gzalready
has the changes you note below in its collector/dsc/Makefile.in.  I
also tried the older one at
http://dns.measurement-factory.com/tools/dsc/download/dsc-200801301758.tar.gz,
which didn't have the diff changes you noted.  So I patched that one and
make/make installed it, but I get the same malloc error.

However, one way I can get any of the versions to run, without getting the
error, is if I run it with the "-d" debug flag.  Whether I do
cd /usr/local/dsc
bin/dsc -d etc/dsc.conf
...or...
/usr/local/dsc/bin/dsc -d /usr/local/dsc/etc/dsc.conf

The program runs correctly, without error and produces the .xml file.

I don't know why that would be -- seems strange to me.  Is that any help?

Thanks,
Ted
