[ecrypt]

When i'am using the component frPreview1 from lazreport.
I try press button preview and press again and again and found out error -->SIGSEGV at address 40E418

frReport1.LoadFromFile('myfile.lrf');
frReport1.Preview:=frPreview1;
if not frReport1.PrepareReport then Exit;
ShowPreparedReport;

Frpreview component of lazreport is running well in Lazarus 1.2.6.

But since using the Lazarus version 1.4 and 1.6.0 and 1.7 I found frpreview of lazrepot experiencing error by showing a warning SIGSEGV at address 40E418, when I press a button to call the program code below repeatedly to display data in frpreview

frReport1.LoadFromFile ('myfile.lrf');
frReport1.Preview: = frPreview1;
if not frReport1.PrepareReport then Exit;
ShowPreparedReport;


Is this perhaps a bug in Lazarus lazreport in versions 1.4 and 1.6.0 and 1.7

sorry i use google translate.
