Xapian devel - Jun 2006 - xapian 0.9.6 build error on debian etch sparc

I'm getting the follwoing error when trying to build xapian 0.9.6 on
debian sparc:

Any ideas?  Looks like a gcc error.

Thanks,

It is.  If you're running the latest GCC 4.0.X you should probably
follow the directions and report it to the GCC team, or perhaps
better to the debian BTS in this case since debian's compilers usually
include a number of patches.

Meanwhile as a workaround, you can try compiling without optimisation
for just the problematic file as that usually helps.  E.g.:

cd matcher
make CXXFLAGS='-g -O0' andmaybepostlist.lo
cd ..
make

"-O0" turns off almost all optimisation.  You might find
"-O1" works
in which case it's probably a better option.

The other thing to try is a different branch - e.g. GCC 4.1 or GCC 3.4.
