<pre>The compiler crashes with the error message below. I'm attaching here the
source that is pretty large, but simply consists of a long sequence of
floating-point operations on a single array. This problem seems to arise
because the source is very long and/or has many functions.
Per instructions in <a href="http://llvm.org/docs/HowToSubmitABug.html#front-end">http://llvm.org/docs/HowToSubmitABug.html#front-end</a>
this seems to be a front-end crash.
