I haven't confirmed yet whether it fixed the ARM problems (due to other issues), but it seems to be causing massive failures on i386:

I can reproduce some of those failures with -O0 and we're not seeing any issues with clang, so I think it's due to your change.  I'm going to revert it for now and re-run the tests to confirm that.
