I've just seen two serious problems with ccache in a short period of
time. In both, webkit seems to be somehow involved (it has a complex
build process).

See <https://bugs.gentoo.org/show_bug.cgi?id=316657> and
<https://forums.gentoo.org/viewtopic.php?p=6262495#6262495>.

I'm afraid we probably can't get enough data from the above to produce a
good bug report for ccache.

What actions would you suggest?
