Very strange failure mode, seen once in our CI and once in a personal job in our CI system on macOS:

[Too many errors, abort]
----------System.err:(1/96)----------
java(88827) MallocStackLogging: can't turn off malloc stack logging because it was not enabled.

All the whitespace is as per the log - which is really weird. No idea where the "too many errors" is coming from - nor the MallocStackLogging message!

Most recent change to Process code was JDK-8364611
