[PATCH] fixes Fortran parameter passing problem

[Wolfgang Gellerich]

Hi Paul,

Andreas Krebbel will commit the patch.

As far as I know there was no PR for this problem. I appended the change
log entry below.

By the way, test case char_result_6 also suggests that there might be a
possible performance improvement as the call to gfortran_string_scan is
actually executed twice. The simplified code provided in my original
message is sufficient to demonstrate that effect.

With best regards,

  Wolfgang Gellerich
