hmm...filed a bug here: https://github.com/golang/go/issues/27929
Could you explain the workaround for this again? I did not understand the fallback option. Apart from that, I tried to run each command manually to force m64 option whenever possible. I was able to get a 64 bit executable for _buildid.o but even after that running ar rcD $WORK/b001/_pkg_.a $WORK/b001/_go_.o $WORK/b001/_buildid.o produces a 32-bit archive. Also, running buildid gives some error about 32 byte hash. Please see: amandeep@s113ldom1:~/workspace$ /usr/gnu/libexec/gcc/sparc-sun-solaris2.11/8.2.1/buildid -w $WORK/b001/_pkg_.a buildid: /tmp/go-build365019570/b001/_pkg_.a: cannot find 32-byte hash in id yqX7tdvlzYS9Aj0X4Sx9/yqX7tdvlzYS9Aj0X4Sx9 Let me know if any of this needs to be reported in the bug or if it provides more clarity on my situation here.
