I'm trying out a High Sierra Mac Book Pro, and Stack appears to work there.

Interestingly enough, I get Poly/ML warnings of the form:

14:11:19 poly(50366,0xb0420000) malloc: *** mach_vm_map(size=8388608)
failed (error code=3)
14:11:19 *** error: can't allocate region
14:11:19 *** set a breakpoint in malloc_error_break to debug

This happens during the build of "HOL-Decision_Procs", which succeeds
regardless:

14:11:19 Finished HOL-Decision_Procs (0:05:36 elapsed time, 0:10:40 cpu
time, factor 1.91)

The timestamp suggests that this happens close to the end of the
session; although no heap image has to be saved for that session.

I'll run some more experiments to figure out if this is spurious or not.
