Bug 139 – Forward reference of enum type doesn't work or crashes compiler

An enum type cannot be forward-referenced at either global or class scope. ---------- D3DTRANSFORMSTATETYPE D3DTS_WORLDMATRIX(int index) { return index + 256; } enum : D3DTRANSFORMSTATETYPE { D3DTS_WORLD = 256, D3DTS_WORLD1, D3DTS_WORLD2, D3DTS_WORLD3 } enum D3DTRANSFORMSTATETYPE { D3DTS_VIEW = 2, D3DTS_PROJECTION, D3DTS_TEXTURE0 = 16, D3DTS_TEXTURE1, D3DTS_TEXTURE2, D3DTS_TEXTURE3, D3DTS_TEXTURE4, D3DTS_TEXTURE5, D3DTS_TEXTURE6, D3DTS_TEXTURE7, // = 23 D3DTS_FORCE_DWORD = 0xffffffff } ---------- enum D3DTRANSFORMSTATETYPE is forward referenced ---------- DMD caused an invalid page fault in module DMD.EXE at 0167:0040b077.

Various other uses, such as declaring a global variable or constant of the enum type, also trigger the error message. Some of them have tests in DStress under enum_* and forward_reference_*, but none I can find at the moment are for the cases of the above example.

Fixed in DMD 0.160
