I ended up doing this. (After receiving some discussion by email).

Remembered that this is an old problem with the old midasServer network
protocol in mana.c - if mana.c is compiled 32-bit, it sends 32-bit pointers, if compiled 64-bit
it sends 64-bit pointers. On the receiving end (in roody), the ROOT TMessage object does not
provide any easy way to tell between them (i.e. object length is reported as 12 or 16 for the two cases).

To make things more interesting, the midasServer code in ROOTANA always sends 32-bit "pointers",
(which are not pointers but 32-bit integer cookies).

I use the ROOTANA midasServer to test ROODY (I have no working mana.c analyzers available),
and ROODY expects to receive 32-bit "pointers", so the two are consistent.

But if I compile my midasServer to send/receive 64-bit "pointers" (cookies), I reproduce this crash. What I can reproduce I can "fix".

If I change the code in ROODY to receive and return 64-bit "pointers" (cookies), both 32-bit and 64-bit midasServer seems to work okey.

This is committed as roody svn rev 248. (https://ladd00.triumf.ca/svn/roody/trunk)

It is the same fix as suggested by Cheng-Ju Stephen Lin [cjslin@lbl.gov].

I hope this helps (or breaks the ROODY midasServer connection for everybody. I hope not).
