Comment:

 I've just pushed some patches that are working towards fixing this
 properly. It turned out to be a more epic task than I expected, but we now
 define the same `callerSaves` function on all platforms. It should now be
 a series of smaller tasks to extend this to the other conditionally-
 defined functions.

 I agree with the comments above that we should keep working towards a
 proper fix rather than implementing temporary workarounds.
