Root macro works on 5.16, bombs on 5.18

I have a GUI histogram-helper Root macro that works fine on Root 5.12, 5.14, and 5.16; I test and use it on Mac OS X, Windows Xp, and Linux. On Root 5.18 it bombs on both Mac OS and Linux (did not try Windows). The user can can open Root files, and can enter an expression to histogram, but when the CreatePlot button is pushed Root crashes. The trace on Linux (Fedora Core 6) is appended below -- the last 4 lines are the only mention of any routines of mine.

I saw nothing in the release notes that indicated any change related to histograms, but a number of Cint changes which I cannot tell if they affect this.

Any suggestions? This macro is large (1900 lines) so I'm not including it here, but I can send it to anyone who wants it.
