i have reproduced crash with steps from configure script.
i tried to reproduce it by gcc-6.3.0 + GNU AS + illumos ld - but it is working
without crash.
problem with gcc-5.4 on SPARC on illumos based platform.
if you want/need access to to SPARC - please let me know - i can provide zone
where you can try reproduce it and use for your investigation.
