--- Comment #1 from Hannes Domani <ssbssa at sourceware dot org> ---
Note that gcc currently doesn't write the name of the parameter pack in the
debug information:

 <2><95>: Abbrev Number: 5 (DW_TAG_GNU_formal_parameter_pack)
    <96>   DW_AT_decl_file   : 1
    <97>   DW_AT_decl_line   : 1
    <98>   DW_AT_decl_column : 35
 <3><99>: Abbrev Number: 6 (DW_TAG_formal_parameter)
    <9a>   DW_AT_type        : <0xaa>
    <9e>   DW_AT_location    : 2 byte block: 91 0       (DW_OP_fbreg: 0)
 <3><a1>: Abbrev Number: 0

Apparently this has been reported already some time ago:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=3D70536

So even if gdb would make use of DW_TAG_GNU_formal_parameter_pack, it could=
n't
show it as `zzargs` in the example.
