<pre>A long expression in a GLSL shader will crash Mesa, the crash occurs after
parsing in generating the HIR from the AST.
Attached is a vertex shader with such a long expression (10,000 add terms).
The bug issue is that although such a shader is not to be found in "real"
applications, a malicious website can use WebGL to crash Mesa which would
likely crash the browser.</pre>
