Hi, the indentation of C-mode is not stable. Here is the recipe
to reproduce the problem:
1. Eval this form in "emacs -Q":
(progn
(switch-to-buffer "tmp.c")
(erase-buffer)
(c-mode)
(insert "int fun (void)\n{\n int a = foo ();\n}")
(c-indent-line-or-region)
(backward-sexp)
(c-indent-line-or-region))
2. Now every time you press TAB-key the indentation of the
bracket alternates between two positions.
By bisecting the source (using the GIT-repo) I found that the
problem comes from:

Enhance `c-parse-state' to run efficiently in "brace desserts".
After reverting that the problem goes away.
