    In case it helps I just checked, using a build I have from
    2010-07-19 and another from 2010-08-02.  The former does not crash;
    the latter does.  So if the difference between those two is
    ENABLE_CHECKING then this would lend support to Eli's hypothesis wrt
    ENABLE_CHECKING.

    These are those builds:

    In GNU Emacs 24.0.50.1 (i386-mingw-nt5.1.2600)
     of 2010-07-19 on 3249CTO
    Windowing system distributor `Microsoft Corp.', version 5.1.2600
    configured using `configure --with-gcc (4.4) --no-opt --cflags
    -Ic:/xpm/include'

    In GNU Emacs 24.0.50.1 (i386-mingw-nt5.1.2600)
     of 2010-08-02 on 3249CTO
    Windowing system distributor `Microsoft Corp.', version 5.1.2600
    
    configured using `configure --with-gcc (4.4) --no-opt --cflags
    -Ic:/xpm/include'

Right.

And thanks for overlooking the lacuna, `--enable-checking'.
