Angle shader compiler halts with certain text

[GoogleCodeExporter]

What steps will reproduce the problem?
1. ShCompile against the below text (I tested it as Fragment Shader):

#ifdef GL_ES,precision mediump float;,#endif,,void main(),{,    gl_FragColor = 
vec4(1.0, 0.0, 0.0, 1.0);,}

2. Angle never returns from this.

What is the expected output? What do you see instead?

Expected: generate an compile-failure error.  Instead, it enters an infinite 
loop.

What version of the product are you using? On what operating system?

Please provide any additional information below.

• Merged into: #40

The validator parses the commas properly, but keeps looking for '\n' at the end 
of #ifdef preprocessor token.
