Hello,

I am having a problem with the root-based analyzer. It crashes when I try to 
analyze multiple runs OFFLINE using the "-i run%05d.mid -o result%05d.root -r 
1 2" feature.

I can reproduce the problem with the example experiment which comes with the 
MIDAS distribution:
Running the analyzer ONLINE works fine: One can start and stop runs one after 
the other, roody shows the histograms being reset and then filled again and 
such.

But OFFLINE, the analyzer crashes when trying to analyze the SECOND run in a 
sequence. So
./analyzer -i run%05d.mid -o result%05d.root -r 1 1   works (only run 1)
./analyzer -i run%05d.mid -o result%05d.root -r 1 3   dies on run 2
Output attached (I added printf's to the "init"-modules, but that's irrelevant 
here)


My own analyzer shows the same effect. There I got the impression the segfault 
happens on the first attempt to Fill/Reset/SetName etc. a histogram in the 2nd 
run. But with the midas example it looks like the analyzer finishes filling 
histos even for run 2, but then dies in eor.

Can you reproduce the problem?

I run MIDAS on an Intel Quadcore, 64 bit SuSE Linux 10.2.
pohl@lamb2:~/midas/examples/root> gcc --version
gcc (GCC) 4.1.2 20061115 (prerelease) (SUSE Linux)

(maybe 4.1.2 "PRERELEASE" is the problem? See message ID 344)

I am using midas rev. 3674 (April 19, 2007), but I got the impression there 
has since not been a change relevant to this problem. Please correct me if I 
am wrong, then I would try it with Rev HEAD.
(My version includes already the fix to the x86_64 segfault problem of message 
ID 337)


Best regards,

Randolf
