Re: Memory Leaks

[Greg Newby <gbnewby@ils.unc.edu>]

There's a great commercial tool called Purify, made by
Rational (www.rational.com).  It's quite pricey ($2400 license),
but you can download a free demo.

It searches for all memory leaks, potential memory leaks, etc.
and tells you where in your code they happen.  Very handy...

I wish I could afford it (we might get an educational version
here at UNC soon).  Meanwhile, I periodically download the 
demo version when I'm having trouble that debuggers can't find.

This doesn't answer your question, but it's a good tool to know
about I think.  It interoperates fine with gdb (that's how I 
use it).  I have not had much luck looking for memory leaks with
gdb - although you can spot a variable that points to unassigned
memory easily enough (e.g., if *p == NULL [0x0]), it doesn't do this
automatically.  Furthermore, it doesn't enforce any kind of 
coding practice, like making sure stuff you 'new' or 'malloc' is
later free'd.
