Yes, Rational Purify. An alternative for detecting memory trashing is
njamd on Linux:

Not exactly, but if you're lucky, memory corruptions are happening
relatively early on, but not biting until much later. If that isn't
the case, it might be less useful. njamd is lightweight enough that
you could potentially run your application with it (inside gdb) all
the time, until it dies.

Cheers,

Duncan.
