No. It does happen with just a make (I use a single core VM at work
for Simple testing) just not very often. I also find that when I am
testing patches that there are some patches that never give me this
problem, but I've never been able to figure it out (for example if it
is just *.cc files patches or *.ly files or some other combination) to
give me any more clues.

I can start to look a bit harder if people want or am happy to test
theories as I, like phil, have a powerful machine so it is only a few
minutes.
