Zooming causes error

[Steve]

Hallo,

i'm using the TeeChart Pro v2015.16.150901 VCL Version with Source Code and D2007.
I have a chart with one lineseries. When i zoom this series again and again i get a integer overflow debugger exception in the PointInPolygon-function.
Is this an known problem or is there a workaround?

Hello,

Could you please arrange a simple example project we can run as-is to reproduce the problem here?

Oh I'm sry. Here's the example. You just have to zoom a few times on the series. When you are in a small point of view there will be an integer error.

Hello,

We haven't been able to reproduce the problem with Delphi 7, RAD XE or RAD 10 Seattle.
I will install RAD 2007 in a virtual machine to check with it too.

Hello,

I've installed TeeChart Pro v2015.16 Source Code on a new Windows 7 x64 virtual machine with a fresh RAD Studio 2007 and I'm not able to make your project to crash zooming on it; there's a moment where the line disappears, but it doesn't crash.

Ok.
I think the problem is that I use the overflow check in the delphi settings for runtime errors. If this is not activated the error doesn't occur. But then at a small point of view the series isn't drawn any more.
