The program example in the bug report violates the f77 standard
ANSI X3.9-1978 FORTRAN 77:

Paragraph 15.7.4 ENTRY Statement Restrictions.
Page 15-13 lines 45 to 50.

"If a dummy argument appears in an executable statement,
 the execution of the executable statement is permitted during      45
 the execution of a reference to the function or subroutine
 only if the dummy argument appears in the dummy argument
 list of the procedure name referenced. Note that the
 association of dummy arguments with actual arguments is bot
 retained between references to a function or subroutine."          50
 
The PR should be closed (if not already).
