Hi,

There is an issue indeed, but it is not a compiler bug but rather a
problem with the RTL. I'll leave the resolution to people working with
WinCE, but it should be rather easy.

I have a problem with bass.dll under wince 6. Lazarus 1.2.6 (fpc
2.6.4) + bass.pas (2.4.11) + bass.dll (2.4.11). Other versions
bass.dll also have this problem. During playback of mp3 files, each
time at a different time from 20 seconds to 5-10 minutes application
crashes. Error text:
"Fatal error. The application has performed an illegal operation and
will be closed. If the problem persists, contact the program
manufacturer.
Exception 0xproject1.eхe "
X32 Windows does not have this problem

example: http://pbcdod.ru/basserror.zip

error - http://pbcdod.ru/scr1.jpg

the program code:

Code: [Select]unit Unit1;

{$mode delphi}

interface

uses
  Classes, SysUtils, FileUtil, Forms, Controls, Graphics, Dialogs,
ExtCtrls, StdCtrls, bass;

  { TForm1 }

  TForm1 = class(TForm)

Label1.Caption:=FormatDateTime('hh:mm:ss',ValPos);
Label2.Caption:=FormatDateTime('hh:mm:ss',ValLen);
if  BASS_ChannelIsActive(channel)=BASS_ACTIVE_STOPPED then begin 
inc(track); if track>2 then track:=1; player; end;
end;

procedure TForm1.Button1Click(Sender: TObject);
begin
BASS_ChannelStop(Channel);
BASS_StreamFree(Channel);
Channel := BASS_StreamCreateFile(false,
PChar(ExtractFilePath(ParamStr(0))+inttostr(track)+'.mp3'), 0, 0, 0 );
BASS_ChannelPlay(Channel, False);
end;

procedure TForm1.Button2Click(Sender: TObject);
begin
 BASS_ChannelPause(Channel);
end;

procedure TForm1.Button3Click(Sender: TObject);
begin
 BASS_ChannelStop(Channel);
end;

procedure TForm1.FormClose(Sender: TObject; var CloseAction:
TCloseAction);
begin
  Bass_Stop();
  BASS_StreamFree(channel);
  Bass_Free;
end;

end.

Help solve the problem. How can I keep track of exactly where to wince
goes wrong? Was anyone has a similar problem and how to solve it?
