Created an attachment (id=546)
two source files and a build batch file to reproduce the bug
It's pretty bizarre. I get a linker error from array expressions which seems to
manifest itself only under the following set of circumstances:
*) using certain complex array expressions,
*) importing the module which does so from another one,
*) specifying both -release and -inline,
*) compiling and linking separately.
Below is an example of an array expression which fails to link:
buf1[] = buf1[] + 0.5f * buf2[];
And here is the output of OPTLINK:
OPTLINK (R) for Win32 Release 8.00.2

Test.obj(Test) Offset 0037AH Record Type 00C3
Error 1: Previous Definition Different :
__arraySliceSliceExpMulAddSliceAssign_f
--- errorlevel 2
I've attached a sample project to demonstrate the problem. Run build.bat to
reproduce. Note that compiling and linking all D files in one step seems to
avoid the issue, but since I want to use Rebuild this is not a convenient
workaround for me.
