Another compiler crash

Another compiler crash

Hello,
when I try to build the following code with either the offline or runtime compiler, it crashes in clang_compiler.dll.

float3 func()
{
float4 a = (float4)(1,1,1,1);
float4 b = (float4)(2,2,2,2);
float3 c = (float3)a / b.x;
return c;
}

The problem is in casting float4 to float3, which according to the specification is illegal.
When I change that line into
float3 c = a.xyz / b.x;
then it compiles fine.

OS: Win7 64-bit
CPU: Core i5
SDK
Version: latest (1.1) (Please consider displaying a revision of the SDK on the download page to simplify referring to the exact version here in
forums)

Could you fix this? The compiler should never crash.
Best regards,
Jiri Matejka
