Great, thanks for the report.

I added "guard" on the 3.15 branch some time back, I think that's the
right fix, although the sync groups feature isn't really used much so
I'm not 100% sure. Applied to 3.14.

We have a proper fix for this 3.15 but I didn't want to pull it into
3.14 as it's a bit more extensive. I changed it to use 'extern'.

This issue should have been fixed already in 3.14.12.5.

Applied, thanks.

No matter how fast light travels, it finds the darkness has
always got there first, and is waiting for it.
