3.2.3 release notes

[Joe Buck]

OK, this one is "really final", since the 3.2 branch is now frozen.
Changes: added 10271, 10336

------------------------------------------------------------------------

This document lists the problem reports (PRs) from GCC's bug tracking
system (GNATS) that are known to be fixed in the 3.2.3 release. This
list might not be complete (that is, it is possible that some PRs
that have been fixed are not listed here).

3.2.3 is a bug fix release only; there are no new features that were not
present in GCC 3.2.2.  Object code and libraries are believed to be
fully binary compatible with code and libraries from previous GCC 3.2.x
releases (though, as always, free software developers cannot provide
any warranties).

To learn more about a particular PR, visit the link

	http://gcc.gnu.org/cgi-bin/gnatsweb.pl

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.

The sorting is slightly different from the GNATS categories, and some of
the titles have been changed to make them more clear.

First, internal compiler errors (ICEs).  These are multi-platform; some
processor-specific ICEs are listed in separate sections below.

 3782 (c++) -quiet -fstats produces a segmentation fault in cc1plus

 8396 ICE in copy_to_mode_reg, in explow.c
 8674 (c++) ICE in cp_expr_size, in cp/cp-lang.c
 9768 ICE when optimizing inline code at -O2
