And for anybody that thinks they have a bug in ccache triggered by some
package.
1. backup the contents of your ccache.
2. Clear the cache.
3. Build once to populate the cache.
4. Build again to build against the cache (once or twice, should have
   identical results).

If step 4 passes, you know you had corruption in your cache.
If step 4 fails, then I'm interested in where it failed, esp. if you can
run the entire process again and repeat the problem on demand.

Note however, that while I have a high level of trust in ccache, I do
think there are more latent bugs in distcc.
