A problem with Cygwin malloc & friends?

I flag the following for the sake of completeness.

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

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@cvs.savannah.gnu.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.
