Subject: Possible issue with epics-base 7 compilation

Hi,

There is a possible threading issue when compiling epics-base 7 using 'make -sj'  on 8 hyperthread system.
Observed on System X 3250 M5 with 8 hyperthreads, running windows 7 Professional, Xeon E3-1230 v3, and Visual Studio 2017.

make -sj never completes compilation
make -sj4 completes compilation

Compilation always successfully completes on Lenovo W550s laptop with 4 hyperthreads. 

The two attached files show the two cases when compiling 'make' and 'make -sj' on the System X 3250 M5 (8 hyperthreads).
