[dsc] dsc malloc() memory corruption error

I have built and installed dsc on a CentOS 5.x (RHEL 5 clone) system running
kernel 2.6.18-164.6.1.el5 but can't get it to run.  When I try starting dsc
I get the following malloc() memory corruption error right away (below).  I
have tried starting it both as root and as the 'dsc' user.  I have tried two
different versions of dsc, today's (Feb. 16) SVN version, "Checked out
revision 12169", and also from the .tar.gz download
dsc-200911111630.tar.gz.  In all cases I get the error.

Any help?

Thanks,
Ted
