Re: [ROOT] Seg Fault in TTreePlayer::Process

Hi Chris,
	This might be due to this version of ROOT being built for egcs 
1.1.2 with glibc 2.1. If you're using RH7 I believe that comes with 
glibc2.2 and some other compiler... Actually, you should probably check 
with Marcel or Urs about which version this is but Linux2 does mean that 
combination to us normally.

						regards,

						Stephen.
