root crashes, cint works?

Hi,

I have an application consisting of the CLHEP 3- and 4-vectors, the CLHEP
lists and iterators and my own class which is based on these. I can
produce a custom application with cint (via makecint) which works ok. When
I create a custom application with root (via rootcint) I get root crashing
in "operator delete. Here are two (edited) example sessions, where I have
narrowed down the problem to creating and deleting a Hep3Vector object:

custom cint:

Everything works fine. 

And here is the same with a custom root:

I work on OSF1 online04.lbl.gov V4.0 386 alpha, a DEC unix 4 system with
the DEC cxx 6 compiler. 

Any ideas? cheers, Stefan
