As far as I can tell the answer is "NO".

It may be a possibility: I had several applications opened (Mathematica,
Safari, ...). Although they were in an "idle" state, they were using some RAM:
several 100Mb out of 4Gb.

The config failure was for the failing build. Looking at the log again, I
noticed that the successful log contained several '#define HAVE_TLS 1' (6
occurrences) while there are none in the log for the failing build. I remember
having seen some fix for tls issues on darwin, but I cannot find the relevant
PR.
