Here's a first draft for GCC 3.2.1 release notes. Please let me know
about anything else that should be mentioned.
Informal release notes for GCC 3.2.1
3.2.1 is a bug fix release only; other than bug fixes there are no new
features that were not present in GCC 3.2.
This document lists the problem reports (PRs) from GCC's bug tracking
system (GNATS) that are known to be fixed in the 3.2.1 release. This
list might not be complete (that is, it is possible that some bug fixes
have been missed).
In addition, the previous fix for PR 7445 (poor performance of
std::locale::classic() in multi-threaded applications) was reverted
("unfixed"), because the "fix" was not thread-safe.
Thanks to Daniel Jacobowitz for doing an early draft of this list.
To learn more about a particular PR, visit the link
and enter the PR number in the "View Problem Report" dialog box. Then
click the "View" button. It's not necessary to log in to view reports.
My sorting is slightly different from the GNATS categories, and I changed
some of the titles to make them more clear.
First, internal compiler errors (ICEs). These are multi-platform; some
processor-specific ICEs are listed below.
