[flang-commits] [flang] [flang] Do not error when `NAMELIST` found within interface body (PR #175079)

[Peter Klausler via flang-commits]

The crash arises from the fact that name resolution defers processing of NAMELIST groups to the end of the executable part of a program or subprogram (so that host association vs local implicitly-typed object don't conflict), and interface blocks don't have an executable part, so the group's names never acquire symbols.  I'll fix it.
