Hmm, we had the last testsuite run for SPARC Linux back in 2013. I was
under the impression it's still being tested... The Solaris version's last
testresult is from 2012...


Which might suggest that the trunk could be broken at this point. :(
And/or completely unprepared for 64bit in any way. Although we still seem
to have a stable 3.0.2 release. Can you try if the stable release built by
us works on your system? Any binary from this.

I don't know anything about SPARC, but if no one else volunteers, I can
take a look. In fact, maybe even a full 64bit SPARC port shouldn't be that
hard (famous last words...), but at least a few weeks of work for sure for
someone who knows the compiler internals.
