Bug 2667 – a few un-demanglable Undefined symbol in std.stdio? compiler bug?

I have an object generated by dmd v2.023, when linking, the linker complains there are some undefined symbols: local.obj(local) Error 42: Symbol Undefined _D3std5stdio21__T6writefTAyaTAyaTaZ6writefFAyaAyaaZv local.obj(local) Error 42: Symbol Undefined _D3std5stdio21__T6writefTAyaTiTiTaZ6writefFAyaiiaZv local.obj(local) Error 42: Symbol Undefined _D3std5stdio19__T6writefTiTAyaTaZ6writefFiAyaaZv These symbols are even un-demanglable: $ ./demangle.exe _D4test3fooAa char[] test.foo but: $ ./demangle.exe _D3std5stdio21__T6writefTAyaTAyaTaZ6writefFAyaAyaaZv _D3std5stdio21__T6writefTAyaTAyaTaZ6writefFAyaAyaaZv any suggestions where I should take a look?

more info: looks like they are all coming from: src/phobos/std/stdio.d:357 and src/phobos/std/stdio.d:413 local.o: In function `_D3std5stdio17__T6writefTAyaTsZ6writefFAyasZv': dmd/bin/../bin/../src/phobos/std/stdio.d:357: undefined reference to `_D3std6format82__T14formattedWriteTS3std5stdio25__T17PrivateFileWriterTaZ17PrivateFileWriterTaTsZ14formattedWriteFKS3std5stdio25__T17PrivateFileWriterTaZ17PrivateFileWriterAxasZv' local.o: In function `_D3std5stdio21__T8writeflnTAyaTAyaZ8writeflnFAyaAyaZv': dmd/bin/../bin/../src/phobos/std/stdio.d:413: undefined reference to `_D3std5stdio21__T6writefTAyaTAyaTaZ6writefFAyaAyaaZv' local.o: In function `_D3std5stdio19__T6writefTAyaTiTiZ6writefFAyaiiZv': dmd/bin/../bin/../src/phobos/std/stdio.d:357: undefined reference to `_D3std6format84__T14formattedWriteTS3std5stdio25__T17PrivateFileWriterTaZ17PrivateFileWriterTaTiTiZ14formattedWriteFKS3std5stdio25__T17PrivateFileWriterTaZ17PrivateFileWriterAxaiiZv' local.o: In function `_D3std5stdio21__T8writeflnTAyaTiTiZ8writeflnFAyaiiZv': dmd/bin/../bin/../src/phobos/std/stdio.d:413: undefined reference to `_D3std5stdio21__T6writefTAyaTiTiTaZ6writefFAyaiiaZv' local.o: In function `_D3std5stdio19__T8writeflnTiTAyaZ8writeflnFiAyaZv': dmd/bin/../bin/../src/phobos/std/stdio.d:413: undefined reference to `_D3std5stdio19__T6writefTiTAyaTaZ6writefFiAyaaZv'

Your demangle is out-of-date. I don't think an up-to-date one exists yet. There's no name mangling problem. Please post a test case.

std.demangle in dmd 2.032 can demangle "_D3std5stdio21__T6writefTAyaTAyaTaZ6writefFAyaAyaaZv". Perhaps related to fixing of bug 2763.

Probably not a bug, no test case given, over two years old. No indication that dmd is at fault.
