I have a TestCase that has this issue.  If I call obj.Free, I am unable to step into the Destroy method and heaptrc indicates a memory leak.  If I call obj.Destroy everything works as expected.  Following the call to Free -
... if (obj nil) then obj.Destroy;
it would seem that the object must be nil. How can I test this? i am unable to step into objpas?.inc.

Thanks, Brian.

You don't need to step in ?

Replace the line Obj.Free with

   if (Obj=nil) then
     Writeln('Error')
   else
     Obj.Free;

Then you'll find the error.

To do what you want you'll need to recompiler everything (RTL, FCL, PAckages etc. with debug information (pass OPT=-gl to the make command line, maybe DEBUG=1 also works)

Michael,

pass OPT=3D-gl to the make command line, maybe DEBUG=3D1 also works

I don't know what this OPT is.  Where can I find out more.

Thanks,
Brian

DOH! that was a display issue OPT=-gl, DEBUG=1

Thanks, Ill try it.

The makefile uses several variables to construct a command-line when compiling units and programs. the contents of the variable OPT is simply appended to the compiler-command-line. make all OPT=-gl
tells make to compile everything and add -gl to the compiler command-line;

You can find more info on compiling the compiler in the appendix of the programmer's manual. (or was it the user's guide ?)
