It's BAAAACK .... Here is the first draft of the bug fix list for 4.0.1. Please let me know about any errors and omissions; suggestions for improved descriptions of bugs are also welcome.
The list will be converted to HTML (I have a Perl script to do most of the work, but it then requires a bit of hand-tweaking of the output) and will be added to http://gcc.gnu.org/gcc-4.0/changes.html . ****ISSUE:**** I have not included the following two bugs because I can't tell if they were in any shipping GCC (e.g. 4.0.0). Can anyone confirm: 21523 [4.0 Regression] 3.4.4 RC1 fails libstdc++ install on powerpc64-linux 21551 ia64-unknown-linux-gnu ia64 bootstrap failed --------------------------------------------------------------------------- This document lists the problem reports (PRs) from GCC's bug tracking system (Bugzilla) that are known to be fixed in the 4.0.1 release. This list might not be complete (that is, it is possible that some PRs that have been fixed are not listed here). 4.0.1 is a bug fix release only; there are no new features that were not present in GCC 4.0.0. Object code and libraries are believed to be fully binary compatible with code and libraries from the GCC 4.0.0 release (though, as always, free software developers cannot provide any warranties). To see details of any bug, visit http://gcc.gnu.org/PR##### , where the ##### is replaced by the actual bug number.
