The 'D' code below was compiling and linking just fine in dmd v0.92, but now with v0.93 and now v0.94 I'm getting a linker error:

<Linker error msg>

C:\dmd>bin\dmd ex1\main_roman.d ex1\roman.d
C:\dmd\bin\..\..\dm\bin\link.exe main_roman+roman,,,user32+kernel32/noi;

roman.obj(roman)  Offset 00148H Record Type 0091
Error 1: Previous Definition Different : _D5roman7isroman5ROMANAa
--- errorlevel 1

</Linker error msg>

Once I move the "const char[] ROMAN = "IVXLCDMivxlcdm";" line out of both of the isroman() functions and to the top of the code, everything then compiles and links nicely again within dmd v0.93 and now v0.94. Walter has already agreed that this is a bug, so I placing it here.
