Strange memory errors

Hi,

We've been seeing some strange memory-related errors lately. Here's
an example from a program that writes objects to a TBranch of a TTree
(this happens after 1,000 objects are written):

CustomReAlloc2: oldsize != size
Fatal in <CustomReAlloc2>: unreasonable size (-4032)

Then it exits. We've also seen other similar messages about delete
and huge sizes, but it's usually only when the program is exiting
normally and could be ignored. We've been experimenting with and seen
this happen with 1.03.09 and 1.03.06 (which was our last "stable"
version, but weird thing have been happening there at times, too,
lately). Does anyone know what could be going on? I think I saw in
another roottalk message that someone else was having problems like
this, so at least it's not just us.

Thanks,
Reid
