From: "nagl46 at web dot de" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug fortran/52111] New: [OOP] procedure pointer with polymorphic passed dummy argument Date: Fri, 03 Feb 2012 16:21:00 -0000 [thread overview] Message-ID: <bug-52111-4@http.gcc.gnu.org/bugzilla/> (raw) http://gcc.gnu.org/bugzilla/show_bug.cgi?id=52111 Bug #: 52111 Summary: [OOP] procedure pointer with polymorphic passed dummy argument Classification: Unclassified Product: gcc Version: 4.7.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: fortran AssignedTo: unassigned@gcc.gnu.org ReportedBy: nagl46@web.de I declare a procedure pointer in an abstract type >> procedure(solve_gen), pointer :: solve with procedure interface >> abstract interface >> subroutine solve_gen(this, val) >> import :: solverAbstract_t >> class(solverAbstract_t), intent(inout) :: this >> integer, intent(inout) :: val >> end subroutine >> end interface Class solver_t is a subclass of solverAbstract_t. Now I want solve to point to >> subroutine solveLeft_sub(this, val) >> class(solver_t), intent(inout) :: this >> integer, intent(inout) :: val >> >> write(*,*) 'i solve left' >> end subroutine Compiling my program with this classes fails with: >>tatanka@tippi:~/tmp$ gfortran main.f90 >>main.f90:66.22: >> >> this%solve => solveLeft_sub >> 1 >>Error: Interface mismatch in procedure pointer assignment at (1): Type/rank >>mismatch in argument 'this' >>main.f90:68.22: >> >> this%solve => solveRight_sub >> 1 >>Error: Interface mismatch in procedure pointer assignment at (1): Type/rank >>mismatch in argument 'this' >>main.f90:74.6: >> >> use m_solver >> 1 >>Fatal Error: Can't open module file 'm_solver.mod' for reading at (1): No such >>file or directory I found this bug in: >>GNU Fortran (GCC) 4.7.0 20120131 (experimental) and in >>GNU Fortran (GCC) 4.7.0 20120120 (experimental). In >>GNU Fortran (Ubuntu/Linaro 4.6.1-9ubuntu3) 4.6.1 program works fine. I also tested the bug on cray with >>hpcatism@eslogin002:~> ftn --version >>/opt/cray/xt-asyncpe/5.06/bin/ftn: INFO: Compiling with >>CRAYPE_COMPILE_TARGET=native. >>/opt/cray/cce/8.0.1/cftn/x86-64/bin/ftn_driver.exe: invalid option -- '-' On cray program also compiled fine and program works.
