Bootstrap failure on Sparc Solaris2.8

[Josh <sundog@mindspring.com>]

I've configured with the following options in a separate objects directory (gcc-objs), using gcc-3.2.3 as the starting compiler:
../gcc-3.3/configure --prefix=/compiler/gcc-3.3 \
--with-ld=/compiler/gcc-3.2.3/bin/ld
--with-gnu-ld \
--with-as=compiler/gcc-3.2.3/bin/as \
--with-gnu-as \
--disable-nls \
--enable-threads=posix

Then:
make CFLAGS='-O' LIBCFLAGS='-g -O2' LIBCXXFLAGS='-g -O2 -fno-implicit-templates' boostrap-lean

The build goes through, completes stage3 compiler, then the following error in eh_alloc.cc:

Any insights?  I tried configuring w/ --enable-threads=single, but that also fails, albeit a different point.  Thanks in advance.
