Could you, please, check the location of Tramp in both cases when /
when not compiled:

M-x locate-library RET tramp-cache RET

OK, that's clear, it's inside `tramp-cache-before-revert-function',
which calls `tramp-flush-file-property' with the parameters (nil nil).
But the code is so short I cannot see the problem. So I'ld like to
wait for your check above. When there are no new evidences, we (you :-)
must either debug that function, or I'll give you some trace messages
to be inserted there.
