--- Comment #1 from Dominik Vogt <vogt at linux dot vnet.ibm.com> ---
It seems that the DWARF library is unable to handle DW_AT_specification:
-- snip --
<1><7b4>: Abbrev Number: 27 (DW_TAG_variable)
<7b5> DW_AT_specification: <0x8b>
<7b9> DW_AT_decl_file : 13
<7ba> DW_AT_decl_line : 77
<7bb> DW_AT_location : 9 byte block: 3 0 0 0 0 0 0 4 80
(DW_OP_addr: 480)
<1><8b>: Abbrev Number: 10 (DW_TAG_variable)
<8c> DW_AT_name : (indirect string, offset: 0x3c4):
secp256k1_nonce_function_rfc6979
<90> DW_AT_decl_file : 14
<91> DW_AT_decl_line : 104
<92> DW_AT_type : <0x98>
<96> DW_AT_external : 1
<97> DW_AT_declaration : 1
-- snip --
DW_AT_name and DW_AT_type are provided by the DW_TAG_variable that the
DW_AT_specification attribute is pointing to. Is that a known problem; ist
there already a fix? Otherwise I can try to make a patch.
