If I change COMPLEX to REAL in the first example, I get % gfcx -c -fdump-parse-tree Namespace: A-H: (REAL 4) I-N: (INTEGER 4) O-Z: (REAL 4) procedure name = log_gamma symtree: 'log_gamma' || symbol: 'log_gamma' type spec : (REAL 4) attributes: (PROCEDURE INTRINSIC-PROC FUNCTION RECURSIVE) result: res Formal arglist: z symtree: 'res' || symbol: 'res' type spec : (REAL 4) attributes: (VARIABLE RESULT) symtree: 'z' || symbol: 'z' type spec : (REAL 4) attributes: (VARIABLE DUMMY(IN)) code: ASSIGN log_gamma:res __lgamma_4[[((log_gamma:z))]] The attributes for log_gamma includes INTRINSIC-PROC, which is clearly wrong.
