Hoi Ric,

I have your tag: 

   iris01>cvs diff -r rf-100902b *.*cc recoilNtp.hh 
   cvs diff: I know nothing about recoilDSysDict.cc
   cvs diff: I know nothing about recoilNtpDict.cc

I make everything from scratch: 

   iris01>gmake -f Makefile clean anaRecoil

It compiles  and links just fine, I run it

   iris01>../bin/Linux24/anaRecoil -c chains/sx-test -y 2 -D .

Much output snipped: 

   ./sx-test.root
   Opened ./sx-test.root

    *** Break *** segmentation violation
   Abort

gdb shows: 

   (gdb) where
   #0  0x40fc0091 in recoilNtp::doSplitOffStudy (this=0xbffa867c, book=true) at splitOff.icc:49
   #1  0x40fcea3e in recoilNtp::bookHist (this=0xbffa867c, dump=0) at bookHist.icc:305
   #2  0x0804d79e in main (argc=7, argv=0xbffff124) at anaRecoil.cc:192

   (gdb) print book
   $1 = true

The problem is that *because* you  have a flag to protect the booking,
the crucial  return from doSplitOffStudy when called  from bookHist is
not  encountered. This  screws  Linux24. I  found  this out  yesterday
night. I fixed it (the hard way), but you did not like my fix.

So, please  provide a tag where  we can run  without getting debugging
trees and histograms for the  splitoff study. ASAP. Else I don't think
we'll have enough time to digest the plots for Friday.


Cheers,
--U.
