Hi
I introduced an boolean-option to the destructor of a class. I
implemented a wrapper without argument for reason of
backward-compability.
This wrapper calls the real destructor with default argument.
Everything worked fine until fpc 2.4 (sample programm below)
When running it compiled with fpc 2.4 i get an Runtime error 216
(segmentation fault).
I could reproduce the problem with the latest svn head.
Without further examination i suggest: The outer destructor tries to
free the memory the inner destructor already released.
So my question:
Is it a bug or am i doing something i should not?
The compiler gives me am note:
test.pas(8,3) Note: Class should have one destructor only
--
Best regards,
Martin
