I have now successfully built and tested 1.0.2c on Solaris 10 with gcc 4.7.2 from unixpackages.com. ./Configure solaris-sparcv9-gcc no-shared -m32 -fPIC -fvisibility=hidden ./Configure solaris64-sparcv9-gcc no-shared -m64 -fPIC -fvisibility=hidden Looks like Solaris Studio is buggy. This bug should be closed.
