Thanks for the hint. I am still scanning the thread and try to reproduce the failures.

I could not reproduce both failures with LDC head. Maybe it is a 2.062 related problem?

I have just taken and installed the latest version, ldc2 on Windows 32 bit (Vista) (LDC - the LLVM D compiler (0.11.0) based on DMD v2.062 and LLVM 3.3svn)):
http://d32gngvpvl2pi1.cloudfront.net/ldc2-0.11.0-mingw-x86.7z

I compile with just:
ldc2 temp.d

And both those programs give the errors :-(

test.d(5): Error: cannot implicitly convert expression (cast(__vector(double[2u]))[1, 2] + x) of type double[] to __vector(double[2u])

test.d(6): Error: incompatible types for ((sum) += (cast(__vector(double[2u]))[x, y] / a)): '__vector(double[2u])' and 'double[]'

I am using the MinGW in the link given by David Nadlinger (gcc version 4.8.0 (rubenvb-4.8.0)):

http://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win32/Personal%20Builds/rubenvb/gcc-4.8-dw2-release/i686-w64-mingw32-gcc-dw2-4.8.0-win32_rubenvb.7z/download

Maybe it's a 2.062 problem, I don't know. But while compiling dmd is a breeze, I don't think I want to compile ldc2 myself. If you think this problem is missing in the ldc2 2.063 then let's ignore this problem until the ldc2 2.063 binary has being released and I can test it again :-)

Bye,
