well, actually finding it was not so hard: The backtrace in the PR pointed me directly to mio_expr, and a bit of debugging showed that we simply do do handle any refs for function calls. > OK for trunk.

One point is that the MOD_VERSION on trunk (11) is already different from the value on 4.8 (10), i.e. it has already been bumped in this release cycle. Moreover the changes I made are "backward-compatible" in the sense that trunk can still read old module files, and also old gfortran versions should still be able to handle modules written by trunk (as long as they don't contain TBP references - however this is anyway prevented by the already-bumped MOD_VERSION).
