Dear ROOTers,
here is the gist of the problem:
-> Operating system is Linux Red Hat 8.0 running on a single Intel
2.4 GHz CPU.
-> Used precompiled version of ROOT Version 3.05/03, gcc 3.2
Problem:
- chain.Process("MyProg.C"); works fine only when I use only one
single file in the chain.Add list,
when more than one file is specified the program goes into
segmentation fault. MtProg.C is generated with MakeSelector. Everything
was fine under 3.02/07
See below
*** Break *** segmentation violation

- Recovery attempts:
I have tried to reinstall from the source code, but after renerating
the libraries and the executables I get again the same error.
If I do a chain.Draw("..."); after specifying the multiple file list
I see no problem.
ANY CLUES?
Thanks,
Franco
