Drawing crashes when histogram title contain special characters

Drawing related segmentation violation occurs when trying to draw a histogram that contains special characters in the title.

PyRoot code to reproduce the issue:

from ROOT import TCanvas, TH1F

canvas = TCanvas('c1', 'Example', 200, 10, 700, 500)

histo = TH1F('name', 'phi_{Medium}_', 100, -4, 4)

histo.Draw()

canvas.Draw()

'phi_{Medium}' is the issue in this case. If another character is appended to the end, for example: 'phi{Medium}_a', the code doesn't crash.

The issue was observed in CMS DQM code: https://cmssdt.cern.ch/dxr/CMSSW/source/DQMOffline/Muon/src/MuonKinVsEtaAnalyzer.cc#109
