on Scientific Linux SL release 5.4 (Boron), the attached macro a.C runs fine in
ROOT 5.27/06b (branches/v5-27-06-patches@36515, Nov 05 2010, 15:46:56 on linuxx8664gcc)
but fails to write output into the output file in
ROOT 5.32/00 (branches/v5-32-00-patches@42372, Jun 14 2012, 16:18:00 on linuxx8664gcc).
I run the macro in the same directory (after switching ROOT version with …/setroot.csh), so I think it is not an issue with (file) permissions, as has been the case with other posts regarding this topic. My output (a.C.txt) is attached.
The behavior is identical with compiled code (works with 5.27/06, but not with 5.32/00).
Code similar to what is in a.C used to work for a very long time. Did I miss an important change? Any hints/help would be much appreciated.
PS: At least on MacOS X, the problem persists with the newer root version
ROOT 5.34/01 (tags/v5-34-01@45048, Jul 20 2012, 15:31:33 on macosx64)
and no output is written into the output rootfile with the same error message. (Initially I thought my problem was Mac OS specific, because I was comparing against 5.27/06 on Linux.)
