Using Root 2.25, built with Visual C++ 6.0 SP3 under WinNT 4.0:
I try to save a canvas as a .root file using either the SaveAs() method or
the interactive menu bar "Save As" command. I get the following root crash:
>D:\Users\Jonathan\Root\DefectPool>root loader.C PlotDP.C

and then root terminates.
Can anyone help me figure out what is causing this crash and whether it's
my fault or the fault of some bug in root. My loader macro loads a fairly
large DLL that worked just fine with root 2.23, and which rebuilt with no
errors or warnings under root 2.25. PlotDP.C is a macro that sets several
parameters and then calls functions in the DLL that do the real work.
Nothing in any of my code involves CustomReAlloc2, so this seems to be an
internal root problem, but I have no clue where to start looking.
As an idiocy-check I tried running hsimple.C in the tutorials directory and
was able to execute c1->SaveAs("foo.root") just fine.
Everything I am doing here worked fine under root 2.23. Nothing in my code
changed, but now root crashes when I try to save the canvas as a .root
file. I can save it as a postscript file with no problem.
Thanks for any assistance,
Jonathan
