Fortran allows the target of a pointer from the evaluation of a
function-reference in a variable definition context (e.g. F2018:R902).
gcc/fortran/ChangeLog:
PR fortran/100218
* expr.c (gfc_check_vardef_context): Extend check to allow pointer
from a function reference.
gcc/testsuite/ChangeLog:
PR fortran/100218
* gfortran.dg/ptr-func-4.f90: New test.
