Subject: gdb-rhbz1976887-field-location-kind.patch

;;Backport upstream patch which fixes internal-error: Unexpected
;;     type field location kind (RHBZ 1976887).

gdbtypes.c: Add the case for FIELD_LOC_KIND_DWARF_BLOCK

The case for FIELD_LOC_KIND_DWARF_BLOCK was missing for
switch TYPE_FIELD_LOC_KIND. Thas caused an internal-error
under some circumstances.

Fixes bug 28030.
