Comment (by cjones051073):

 On my 2015 MBPro here it probably takes something in the region of 4 hours
 to build. So those time over 12 hours definitely point to something else
 going on, and I would agree it sounds like that is probably memory issues
 on the buildbots, as not having any feedback during the build for 1 hour
 is also not normal.

 I don’t think there will be much I can do to reduce the memory usage of
 individual clang processes (and yes for complex build units 5gb is not
 uncommon sadly) but i could look into if reducing the parallelism in the
 builds can be done. That won’t help with the overall build time, but would
 mean the machine would be less stressed at any given point....
