build problem with recent snapshot

[Giorgos Keramidas]

Recent build with GTK+ have been crashing randomly here, so I tried
building a recent snapshot with -DENABLE_CHECKING and the following
environment variables:

    export CPPFLAGS='-DENABLE_CHECKING'
    export CPPFLAGS='-DENABLE_CHECKING'
    export CFLAGS='-O2 -pipe -ggdb'
    export CC='gcc'
    export CONFIG_SHELL=/bin/sh
    export MAKE='gmake'

Then I configured and tried to build Emacs with:

    $ ./configure --prefix=/opt/emacs --with-x --with-xpm \
        --with-jpeg --with-tiff --with-gif --with-png \
        --with-gtk 2>&1 | tslog | \
        tee ~/tmp/config-emacs-2006.05.18.02.20.39-freebsd7.0-i386-trunk.log
    $ gmake bootstrap 2>&1 | tslog | \
        tee ~/tmp/build-emacs-2006.05.18.02.20.39-freebsd7.0-i386-trunk.log

The 2006.05.18.02.20.39 snapshot is the last commit of CVS that has been
merged into the local source tree.

But enabling the CPPFLAGS and CFLAGS shown above in the environment made
things much worse; now Emacs fails to bootstrap on FreeBSD 7.0-CURRENT
(i386), with the following stack trace from `bootstrap-emacs'.

Any help about why this could happen, or ideas about tracking down the
real problem?
