Hi Philipp, please keep "Cc: 58005@debbugs.gnu.org" when you reply so
that the thread of the discussion remain in the bug tracker.

Thank you for your reply. It's probably true that `buffer-base-buffer'
makes `buffer-file-name' usable in indirect buffers. However, what I'm
worrying is that other potential incompatibilities sparsely continue to
pop up and each ad-hoc deal eventually amounts to make AUCTeX unstable,
given a lot of subtlety regarding to `TeX-master-file'.[1]

Any takers out there? (My preliminary idea is, as I wrote in my previous
message, to modify C-c C-c and alikes so that they suggest to switch to
the base buffer and run there when they are called in an indirect
buffer.)
