Has OpenDialog been created at this point? Better to double check by changing to
if Assigned(OpenDialog) then
OpenDialog.Execute
else
raise Exception.Create('OpenDialog not yet created');

Hi,
I wrote a small program for Linux in a previous version of Lazarus which
compiled and ran without problems before. I have now updated to fpc 3.0.0 and
Lazarus 1.6 (backports version for Debian X86_64 Jessie). The code still
compiles perfectly (it had a number of warnings, but these have now
disappeared: e.g. unixfileutil.inc(6,51) Warning: Symbol "UTF8ToSys" is
deprecated: "Use the function in LazUTF8 unit"), but it results in a runtime
error
"Project birds raised exception class 'External: SIGFPE'.
At address 7FFFEF8FC57F"
when running the following code:
procedure THoofVrm.OpenBtnClick(Sender: TObject);
begin
OpenDlg.Execute;
end;
What is wrong with my code (and how should I change it)?
I know that there has been a change in FPC/Lazarus string implementation, but
this is just a standard Lazarus File Open dialog (TOpenDialog) and result in
the error before even allowing me to select the file to open.
I am not using either UTF8ToSys or even the unixfileutil unit AFAICT:
"uses
Classes, SysUtils, FileUtil, LResources, Forms, Controls, Graphics, Dialogs,
IpHtml, StdCtrls, ExtCtrls, Buttons, ExtDlgs, AsyncProcess, Ipfilebroker,
strutils, Soek;"
Any pointers appreciated...
Regards,
Chavoux
Just a wild guess. The villain might be some property (such as FileName, Filter
or InitialDir) that you did set up with old Lazarus at design time and which
isn't compatible with current version. Revising the design time properties of
your File Open Dialog with Object Inspector should fix the issue.
