I've just built ECL and I'm getting regular crashes which I narrowed
down to this commit.

The build machine is a Linux/x86 with glibc 2.7 and gcc 4.1.2, and I
used this configuration:
--prefix=/usr --host=i686-pc-linux-gnu --mandir=/usr/share/man
--infodir=/usr/share/info --datadir=/usr/share --sysconfdir=/etc
--localstatedir=/var/lib --with-system-gmp --enable-boehm=system
--enable-c99-complex --enable-asmapply --enable-smallcons --without-cxx
--enable-threads --with-__thread --enable-unicode --without-x
--without-clx --build=i686-pc-linux-gnu

A typical crash:
