--- Comment #3 from Mark Wielaard <mark at klomp dot org> ---
Trying to track down why/how this could happen, the following might be useful:

The abstract_origin is this variable:

 [3d8fe0]        variable             abbrev: 178
                 name                 (string) "f16"
                 decl_file            (data1) qfloat16.h (11)
                 decl_line            (data1) 171
                 decl_column          (data1) 12
                 type                 (ref4) [3d8fb3]

With the following type:

 [3d8fb3]    base_type            abbrev: 80
             byte_size            (data1) 2
             encoding             (data1) float (4)
             name                 (strp) "__fp16"

This might explain why it only happens on arm, which is afaik the only arch
that has __fp16 as builtin type.
