--- Comment #11 from Luis Machado <luis.machado at linaro dot org> ---
Ok. I may have found a clue.

The problematic binary seems to have the following for the str's type
description:

<1><1074>: Abbrev Number: 25 (DW_TAG_string_type)
    <1075>   DW_AT_string_length: 5 byte block: 99 46 3 0 0     (DW_OP_call=
4:
<0x1066>)
    <107b>   DW_AT_sibling     : <0x108a>

The working case (Ubuntu 18.04) seems to have the following:

<1><114c>: Abbrev Number: 27 (DW_TAG_string_type)
    <114d>   DW_AT_string_length: 5 byte block: 99 55 3 0 0     (DW_OP_call=
4:
<0x112d>)
    <1153>   DW_AT_byte_size   : 4
    <1154>   DW_AT_sibling     : <0x1162>

So it seems we're missing a DW_AT_byte_size entry.
