--- Comment #2 from martin <mscfd at gmx dot net> ---
I further tried to find out what the call to find_symbol (this is the call
which consumed the compilation time) is achieving in read_modules(). Even w=
ith
the accidentially wrong patch everything just seems to work (and I have lot=
s of
generic interfaces and submodules etc., for which there are checks in
read_modules following the call to find_symbol).

With some printf's I at least checked the the corrected patch definitely fi=
nds
the symbols it is looking for. But I cannot come up with some testcase show=
ing
that find_symbol returns the expected result in read_modules().=
