Bug 17367 – CodeView/MSCOFF: bad debug information for enumerators

Compile: module test; enum E { one, two } with "dmd -m64 -g -c test.d" and analyze it with cvdump from https://github.com/Microsoft/microsoft-pdb/tree/master/cvdump: ... *** TYPES 0x1000 : Length = 22, Leaf = 0x1507 LF_ENUM # members = 2, type = T_INT4(0074) field list type 0x1001 enum name = test.E 0x1001 : Length = 22, Leaf = 0x1203 LF_FIELDLIST list[0] = LF_ENUMERATE, none, value = 0, name = 'one' Error : Leaf is not aligned on a 4 byte boundary list[1] = LF_ENUMERATE, none, value = 1, name = 'two' 0x1002 : Length = 42, Leaf = 0x1504 LF_CLASS # members = 0, field list type 0x0000, FORWARD REF, Derivation list type 0x0000, VT shape type 0x0000 Size = 0, class name = object.TypeInfo_Enum Note the reported misalignment which can cause debuggers to get really confused.
