Description
hi -
Trying to open a ROOT file that wan't properly closed with root 6.14.04
can lead to an infinite recursion in TFile::GetStreamerInfoListImpl.
(Tested with the LCG_94 version.)
An example of such a bad file is attached. Trying to open it
with TFile::Open leads to an infinite recursion between two sites:
#250 0x00007ffff0457c75 in TFile::GetStreamerInfoList (this=0x32a0800)

#251 0x00007ffff0457b4e in TFile::GetStreamerInfoListImpl (this=0x32a0800,

lookupSICache=false)

#252 0x00007ffff0457c75 in TFile::GetStreamerInfoList (this=0x32a0800)

While the file is evidently corrupt, ROOT should handle it by giving
an error rather then going into an infinite loop.
