Just to make sure what you mean by identical output: the resulting .o or
the preprocessed output of gcc -E? If the preprocessed output is not
identical for the two runs, there will be a cache miss even if the
resulting .o files are identical.
It may be helpful to turn on CCACHE_LOGFILE and try to see what ccache
says that way.
Also, does "ccache -s" show the same stats on the different hosts?
