[Lunderberg]

I'm having difficulty reproducing the issue. When compiling against ROOT 6.06/02, I can start the open a raw file, produce and draw histograms, then use the FitPanel on those histograms as they filled.

Which version of ROOT are you using, and what was the behavior leading up to the crash?

[placebosarah]

I'm using ROOT 6.06/04. I open the GUI using attached script, and a bunch of warnings appear (as below- these always appear when processing data- not sure if relevant). I open a 1D histogram while filling and attempt to fit using Fit Panel. The fit appears successful (as in original post) and then there is a segmentation fault. The fault occurs almost every time, but there have been occasions where I have performed one successful fit without issue, before the segmentation fault occurs on the second fit.
