Copyright (c) 1993-2009 by Florian Klaempfl
Target OS: Linux for x86-64
Compiling project1.pas
Error: Operator is not overloaded
project1.pas(18) Fatal: There were 1 errors compiling module, stopping
Fatal: Compilation aborted
Error: /home/myname/lib/fpc/2.5.1/ppcx64 returned an error exitcode (normal if you did not specify a source file to be compiled)
$

Additional information:

- Not tested if reproducible on other platforms/architectures.

- Discussion went here:
http://www.mail-archive.com/fpc-pascal@lists.freepascal.org/msg18933.html

- If possible, it would be nice if the compiler error message could provide a little bit more information (e.g. line number, what operator).
