The solution was to properly comment that this was a gcc issue, in that this is a spurious error, does not appear in previous gcc versions, and has been fixed in later gcc versions. Setting 'jump' to NULL may hide reall issues in case the code is changed in the future, so it is not appropriate a fix. Hence why the previously- submitted patches were not applied. I'll take this on me to properly fix this. Thanks for the heads up. Regards, Yann E. MORIN. -- .-----------------.--------------------.------------------.--------------------. | Yann E.
