The problem for (...) expressions is:
In match_primary, several gfc_match_* are called, which all return MATCH_NO,
until gfc_match_char ('('), which returns true. (So far so good.)
However, before "gfc_match_char" there is a call to gfc_match_rvalue.
gfc_match_rvalue calls gfc_match_name -- and the latter not only returns
MATCH_NO, but also issues
if (gfc_error_flag_test() == 0)
gfc_error ("Invalid character in name at %C");
which is at the heart of the problem. Without the call to gfc_error, the
program works.
The next question is how to solve this without breaking the diagnostics. I'd
assume this affects much more expressions than this one.
I was thinking of a flag (like "bool match_only"), which means that on needs to
audit all 37 uses of gfc_match_name.
