The warning that becomes an error is:
z:/build/build/src/layout/base/nsCSSColorUtils.cpp(24): warning C4305: 'initializing': truncation from 'double' to 'float'

How can that be intermittent?
The code that triggers the warning was added in bug 1382896, but that didn't appear because the msvc builds don't happen on inbound, apparently.
