Some bug reports_(re)

Hallo, Frank; hello, everybody!

According to Frank Heckenbach:

Hmmm ... I am redirecting stderr all the time ... what OS are you using?
With DJGPP and the BPcompat package, redirection is turned off when
DirectVideo is `true'.  (And redirection is not easy with DJGPP anyway.)
It works fine on my Linux box.

Okay.  I am adding it to my bug list.  Thanks.

Okay.  I am adding it to my bug list.  Thanks.  :-)

Workaround:  GPC has no problems to deal with structures above 65520 bytes.
(It has a 4GB limit instead.)  So you can just write:

    Const
      MaxVar = 1000000;  (* large random number *)

    Type
      X = Integer;
      XArray = array [ 1..MaxVar ] of X;

Okay.  I am ... etc. :-)

That's not necessary.  I have the example program, so I will be able to
reproduce the bug.  (I hope at least.)

Also thanks for the detailed description in which situations the bug
occurs. :-)

Return.

But I am planning to support `Exit' as an alternative to it.
