[Patch, Fortran, Regression] PR 48059: ICE in in gfc_conv_component_ref: character function of extended type

[Janus Weil]

Hi all,

the attached patch fixes the PR in the subject line. The problem was
the following: During the interface mapping for a procedure call we
need to take special care of polymorphic arguments, since the type of
the actual argument can differ from the type of the formal argument.
Therefore we need to replace the base type of component references by
the actual type (in particular to get parent references right).

The patch was regtested on x86_64-unknown-linux-gnu. Ok for trunk?

Cheers,
Janus
