Is this the same error as above, with the corrupt autorelease pool?

This is an interesting little bit of code with a comment saying it's
been added to cover for what sounds like a bug in macOS 10.10...
Perhaps it's worth removing it and seeing if that helps.

The code's around nsterm.m line 4569, and the whole #ifdef'd section
should be removed.

I still suspect that if we have a corrupt autorelease pool, the
problem will be somewhere entirely different...
