The following error occurs while compiling template code (included as
error-4.2.2.ii at the tail of this report).

The same error occurs reliably on both Linux/Intel and Solaris/Sparc

on Linux gcc -v produces:
> Using built-in specs.
> Target: i686-pc-linux-gnu
> Configured with: ../gcc-4.2.2/configure --enable-languages=c,c++ --prefix=/data/rosa2/build/gcc/ins-4.2.2-Linux-i686
> Thread model: posix
> gcc version 4.2.2

On Solaris gcc -v produces:
> Using built-in specs.
> Target: sparc-sun-solaris2.8
> Configured with: ../gcc-4.2.2/configure --prefix=/space/snail/gl17859/test-4.2.2/tools --with-threads=posix --with-as=/usr/ccs/bin/as --with-ld=/usr/ccs/bin/ld --enable-shared --with-cpu=v9 --enable-languages=c,c++
> Thread model: posix
> gcc version 4.2.2

Note that the error does not occur with gcc 4.1.0:
