Yeah, this bug pretty much made me switch to clang on my devel machine..
(I still use gcc on VMs, though, so most patches get compiled with both)
There are 3
workaround for this bug:
A: remove package ccache
B: enable warning with flag -Wsystem-headers
C: decrease value of track-macro-expansion (default is 2)
-ftrack-macro-expansion=0
