RE: [ns] Memory problems

Hi.

I installed ccmalloc-0-3-4, and added the following two lines to the ns
Makefile after LIB = etc.

-L/usr/local/lib -lccmalloc \
-L/usr/local/lib/ccmalloc-gcc.o \

The make runs successfully but on invoking ns, I get a core-dump. Gdb
tells me that there's some problem with /lib/libc.so.6 Can anyone please
help?
