Mark: "I seem the same issues on OS X (10.9.5) when compiling with clang 4.0 from MacPorts. So this doesn't seem to be FreeBSD-specific." I confirm, I reproduced the bug on Linux using Clang 4.0. Mark: "But if that's what we have to do to maintain correctness with clang, then I guess we have little choice." I pushed my change adding -fno-strict-aliasing compiler option to clang. I created the issue #30124 to fix the aliasing issue in dtoa.c. I didn't check yet if we have to backport the -fno-strict-aliasing change, maybe we can wait until the aliasing issue is fixed and backport this future fix?
