--- Comment #3 from James Clarke <jrtc27 at jrtc27 dot com> --- I believe the problem is in the "m" type in runtime2.go. There are 4 bools in a row, which is fine, as they will take up 4 bytes, but then "printlock" is an int8, which means "fastrand" will only be 2-byte aligned. This continues with "ncgocall" and "ncgo" being 2-byte aligned, and then the "park" field will also be 2-byte aligned only. Is there a way to tell gcngo that the "note" struct (and in theory the "mutex" struct too, since that will be a futex, and I don't know if anything embeds it incorrectly-aligned) should be 4-byte aligned, i.e. an equivalent of __attribute__((aligned(4)))?
