https://gcc.gnu.org/bugzilla/show_bug.cgi?id=104312 --- Comment #3 from CVS Commits --- The master branch has been updated by Harald Anlauf : https://gcc.gnu.org/g:2273fd5a6fdbe8f7da2c0e217c279bcbaaa7df9e commit r13-7146-g2273fd5a6fdbe8f7da2c0e217c279bcbaaa7df9e Author: Harald Anlauf Date: Tue Apr 11 21:44:20 2023 +0200 Fortran: fix functions with entry and pointer/allocatable result [PR104312] gcc/fortran/ChangeLog: PR fortran/104312 * resolve.cc (resolve_entries): Handle functions with ENTRY and ALLOCATABLE results. * trans-expr.cc (gfc_conv_procedure_call): Functions with a result with the POINTER or ALLOCATABLE attribute shall not get any special treatment with -ff2c, as they cannot be written in Fortran 77. * trans-types.cc (gfc_return_by_reference): Likewise. (gfc_get_function_type): Likewise. gcc/testsuite/ChangeLog: PR fortran/104312 * gfortran.dg/entry_26.f90: New test. * gfortran.dg/entry_27.f90: New test.

The issue may be clearer if the testcase is extended as follows: function f() real, pointer :: f, e real, target :: a(2) f => a(1) return entry e() e => a(2) end so that one gets (before the traceback): pr104312-zz.f90:5:8: 5 | return |1 Error: pointer value used where a floating-point was expected pr104312-zz.f90:8:3: 8 | end | 1 Error: pointer value used where a floating-point was expected pr104312-zz.f90:1:0: 1 | function f() | internal compiler error: in fold_convert_loc, at fold-const.cc:2504 Setting a breakpoint in gfc_generate_return and checking the fndecl, one sees that it is wrong for -ff2c.
