Comment 1 Jan Kratochvil 2008-05-07 20:09:38 UTC

* Fri Apr 11 2008 Jan Kratochvil <jan.kratochvil> - 6.8-2
- Fix a regression due to PIE of reloading a changed exec file (BZ 433410).

Upstream: http://sourceware.org/ml/gdb-cvs/2008-05/msg00053.html

Fixed i Bug 433410 but it unfortunately did not make it for F-9 GA.
It is expected to be released soon after the GA release as an update.
Please do not ask why, this is the Fedora release management. :-)
