           Summary: a few un-demanglable Undefined symbol in std.stdio?
                    compiler bug?
           Product: D
           Version: 2.023
          Platform: PC
        OS/Version: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla@digitalmars.com
        ReportedBy: someanon@yahoo.com


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

Your demangle is out-of-date.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.
