The attached project uses a NaN value in a series to create a break in
the curve. When the "logarithmic" checkbox is clicked to draw a log y
scale the program crashes with an external SIGFPE in
TLogarithmAxisTransform.AxisToGraph.

Fixed in r35659.

By the way, I have recently added another axis intervals control
property:
try setting LeftAxis.Intervals.Tolerance = 5 with aipGraphCoords
option.

Thank you, the NaN is now handled correctly.

The tolerance = 5 produces much nicer labels than the default
settings, I agree.
