I flag the following for the sake of completeness.


I have the habit to build Emacs from CVS almost weekly, without big
problems.

Recently the unicode branch of Emacs was merged to trunk. Since then,
the build fails as described here [1].

I have tried with: GCC-3.4.4, 4.0.4, 4.1.2, 4.2.2, 4.2.3; with
Cygwin-1.5.25-7, 1.5.25-5, 1.5.24-2 (Jan. 2007) and the snapshot 20080129.

In all cases it fails in the same manner [1]!

I have posted this on emacs-devel and the conclusion seems that,
perhaps, the problem is in malloc & friends [2].

The following steps should reproduce the failure (until the unicode
branch was merged, I never met it):

cd /tmp
cvs -z3 -d:pserver:anonymous AT cvs DOT savannah DOT gnu DOT org:/sources/emacs co -P emacs
mkdir -p /tmp/build
cd /tmp/build
/tmp/emacs/configure --with-x-toolkit=lucid
make bootstrap


If I remember correctly, malloc and/or gmalloc had caused problems in
the build of Emacs with the GTK support (and this forced us to
configure --with-x-toolkit=lucid). The thing was discussed for a while
on this list.


Cheers,
    Angelo.
