freebsd stable - Jan 2014 - upgrade_checks fails on stable/10 in parallel builds?

Colleagues,

after upgrading my builder to stable/10 I'm getting consistent errors like

--- upgrade_checks ---
A failure has been detected in another branch of the parallel make

make[1]: stopped in /FreeBSD/pristine/src.9.2
*** [upgrade_checks] Error code 2

make: stopped in /FreeBSD/pristine/src.9.2
1 error

make: stopped in /FreeBSD/pristine/src.9.2

in case of using -j when invoking buildworld

make -DNO_CLEAN upgrade_checks (without -j) rebuilds (f)make fine, and then 
parallel buildworld seems to work fine.

Any thoughts?  I'd tried to look at Makefiles, but lost in the middle ;)

Thanks!

Well, I spoken too soon: on second phase, the buildworld chokes on libstdc++.

Moreover, subsequent make goes further, not deterministic on failing.

Will try to test more thoughly tomorrow...

Make sure you try going all the way through the build without the -j
option. If you haven't already tried that, it's possible that the
problem would occur there too, and the parallel build is just obscuring
the output, not actually failing in a different place.
