<div>
<pre>There is a bug in the front-end where an array of a structure, which was
declared as incomplete structure first, ends up not getting a size assigned to
it.
Example - t.cpp:
struct A(*p)[3];
struct A { int f; } a[3];
command: clang -g -c -S -emit-llvm -o - -x c++ -gcodeview t.cpp
!6 = !DICompositeType(tag: DW_TAG_array_type, baseType: !7, elements: !11)
!7 = distinct !DICompositeType(tag: DW_TAG_structure_type, name: "A", file: !1,
line: 2, size: 32, align: 32, elements: !8, identifier: ".?AUA@@")
!8 = !{!9}
!9 = !DIDerivedType(tag: DW_TAG_member, name: "f", scope: !7, file: !1, line:
2, baseType: !10, size: 32, align: 32)
!10 = !DIBasicType(name: "int", size: 32, align: 32, encoding: DW_ATE_signed)
!11 = !{!12}
!12 = !DISubrange(count: 3)
Where it should be:
!6 = !DICompositeType(tag: DW_TAG_array_type, baseType: !7, size: 96, align:
32, elements: !11)</pre>
