This program, arrayop.d,
void main()
{
double[4] a;
double[4] b;
a[] = b[] + b[];
}
compiled and run repeatedly in a batch file
dmd arrayop
arrayop
dmd arrayop
arrayop
dmd arrayop
arrayop
... (I put it in about 20 times)
eventually generates this error on a SandyBridge processor, Windows 7.
C:\sandbox\bugs>dmd arrayop
DMD v2.055 DEBUG
OPTLINK (R) for Win32 Release 8.00.12

OPTLINK : Error 3: Cannot Create File arrayop.exe
--- errorlevel 1
Also happens in release version of DMD 2.055.
I think it is an SSE issue, since it only happens with arrays of floats and
doubles (not reals). But I'm just guessing. Maybe it is corrupting the stack.
