Brilliant advice, Bruce! This was indeed the cause. The secondary process
had some shared libraries mapped right in the middle of the viable 1G range.
The most expedient workaround was to link the primary process against those
same shared libraries, as you advised Etai here:

Perhaps not the most sustainable solution...
