Hi there!
I've got so unusual error?! I'm quite sure that my source code is OK, there's no problem. What's happened?! Compiler said that's all OK, app is OK. When I put simple procedure, lbl->on click I've got:
{

---

lclproc code

---

procedure RaiseGDBException(const Msg: string);

Raises an exception.
Normally gdb does not catch fpc Exception objects, therefore this procedure
raises a standard "division by zero" exception which is catched by gdb.
This allows to stop a program, without extra gdb configuration.

}
procedure RaiseGDBException(const Msg: string);
begin
debugln(rsERRORInLCL, Msg);
// creates an exception, that gdb catches:
debugln(rsCreatingGdbCatchableError);
DumpStack;
if (length(Msg) div (length(Msg) div 10000))=0 then ;
end;
//

Before that, works excellent!?
Win7 Ultimate 32bit CT2.7 (BigIde).
Thank you.

Hi, I found this(lazarus bugtracker): Closing multiple files with Ctrl F4 raises sometimes a division by zero exception. Happened twice in last week.

I tried to create new project and add all forms but without success...
Fortunately, I found older backup and resolve problem.
Regards.
p.s. The lesson, create an incremental backup!!!

Yes, always you must make a backup

Finally!
The problem is *.lfm unit,which is not saved properly. Of course there is so many reasons for that(maybe too many changes in table structure, copy-paste, etc.).
Create new one in this case is safe way.
Regards.
p.s. It's my mistake!
