Crash in 3D chart

Post by Art » Thu Dec 14, 2017 12:50 am

I am using VCL 2015 (TeeChart2015RADXE2.exe) with Dephi XE2. On some computers (not all of them) I get the following stack trace with a creash deep in the steema code, when the 3D chart is rotated, what could be causing it and how could it be fixed:

exception class : EAccessViolation
exception message : Access violation at address 00000000010FC4C1 in module 'test_x64.exe'. Read of address 0000000000000008.

Hello,

The ExistFourGridIndex method is probably accessing some invalid index of GridIndex array.
Could you please arrange a simple example project we can run as-is to reproduce the problem here?
