R help - Apr 2007 - Need mtrace (malloc debugging) help

Hi all,

I am using "mtrace" malloc debugging utility to trace memory leaks in
my
application.

I followed following steps:

1. Added mtrace() function in the beginning of my main function.
2. exported the MALLOC_TRACE environment variable.
    $ export MALLOC_TRACE=memory.log
3. Run the program
4. trace the program for memory leaks.
    $ mtrace <myprogram> $MALLOC_TRACE

But In 3rd step above, my system is hanging.

Could anybody please help me to come out of this problem.

If anybody have another solution for finding out memory leaks, then it is
always welcome.


Thanks & Regards,

Sharad.

Most of us use valgrind, including on R itself.  It does much more.
