Summary: -gdwarf-4 bug
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: debug
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: tro...@gcc.gnu.org
Compile this program with '-gdwarf-4':
class C { public: C() { } };
namespace X {
typedef struct {
C m;
} t2;
t2 v;
};
The definition of the constructor for t2 is emitted weirdly.
I see:
<1><72>: Abbrev Number: 21 (DW_TAG_structure_type)
<73> DW_AT_declaration : 1
<73> DW_AT_sibling : <0x80>
<2><77>: Abbrev Number: 22 (DW_TAG_subprogram)
<78> DW_AT_name : t2
<7b> DW_AT_artificial : 1
<7b> DW_AT_declaration : 1
<7b> DW_AT_object_pointer: <0x1b5>
... but note that there is no way to associate this with the type 't2'.
If I use plain -g, I see what I would expect: the constructor is a child
of the type 't2':
<1><79>: Abbrev Number: 10 (DW_TAG_structure_type)
<7a> DW_AT_specification: <0x5d>
