compile, run, and close. You'll get an AV and many memory leaks.

it is the version from http://cc.embarcadero.com/item/29708 (the original delphi xe5 version contains this bug also)

there was no such bug in delphi xe.

Problem has been fixed. An updated will be available soon.
Sorry for the incovenience.
A workaround is described at Embarcadero Quality Central database:

QC122729

http://qc.embarcadero.com/wc/qcmain.aspx?d=122729

The workaround is, before destroying the DBChart Series or closing the form, call the protected RemovedDataSource method, passing the Series and Series DataSource, like:

type
  TChartAccess=class(TDBChart);

 TChartAccess(DBChart1).RemovedDataSource(Series1,Series1.DataSource);

This must be done for all series that have Datasets as DataSource.
