The issue is:
[ 69] class_type
name (string) "C"
byte_size (data1) 8
decl_file (data1) 1
decl_line (data1) 11
containing_type (ref4) [ 69]
sibling (ref4) [ aa]
[ 77] inheritance
type (ref4) [ 57]
data_member_location (sdata) 0
accessibility (data1) public (1)
[ 7e] member
name (strp) "_vptr.C"
type (ref4) [ bc]
data_member_location (sdata) 0
artificial (flag) Yes
class__fprintf sees the inheritance and member at the same
data_member_location and skips the member (which contains the real
size).
You could work around it with the following patch:
diff --git a/dwarves_fprintf.c b/dwarves_fprintf.c
index 23da5b1..90d830a 100644
--- a/dwarves_fprintf.c
+++ b/dwarves_fprintf.c
@@ -1386,8 +1386,7 @@ size_t class__fprintf(struct class *class, const

/* XXX for now just skip these */
- if (tag_pos->tag == DW_TAG_inheritance &&
- pos->virtuality == DW_VIRTUALITY_virtual)
+ if (tag_pos->tag == DW_TAG_inheritance)
continue;
/*
Just ignoring the virtuality. But I don't really understand the special
casing and sizing issues around inheritance. So why this works is a
mystery to me atm.
Cheers,
