locally i think ive never seen an issue and i use it 100% of teh time for all builds. in fate clients, i have seen cases where ccache needed to be cleared I dont want to guess the cause as its just a guess, but clients run out of disk space, they run out of memory which doesnt happen to me locally nearly that often > Gentoo stopped accepting bug reports if ccache was involved and it wasn't > reproduced without it. > The builds are speedy enough that a full build each time doesn't seem too > horrible.

Because without that you have random temporary files and so they are not cached. my configure here takes 6sec (with --tempprefix and ccache and lots of --enables) without tempprefix its 10sec thx [...] -- Michael GnuPG fingerprint: 9FF2128B147EF6730BADF133611EC787040B0FAB While the State exists there can be no freedom; when there is freedom there will be no State. -- Vladimir Lenin
