           Summary: [REG 2.099] compiling mutliple files without linking
                    produces broken object files
           Product: D
           Version: D2
          Hardware: All
                OS: Windows

Compile these two files:

// xfile.d
module file;

// xstring.d
module xstring;

string[] tokenizeArgs(string text)
        return [];



 dmd -m32mscoff -c xfile.d xstring.d 
and link them with // main.d import xstring; void main(string[] args) { auto arr = tokenizeArgs(args[0]); } via
 dmd -m32mscoff main.d xfile.obj xstring.obj
causes xstring.obj : error LNK2005: __D5xfile12__ModuleInfoZ already defined in xfile.obj main.obj : error LNK2019: unresolved external symbol __D7xstring12tokenizeArgsFAyaZAQf referenced in function __Dmain main.exe : fatal error LNK1120: 1 unresolved externals Error: linker exited with status 1120 a) xstring.obj contains a definition for the module xfile b) the symbol for tokenizeArgs is missing from xstring.obj Looking at the object files, it seems xfile,obj is repeated inside of xstring.obj --
