I'm getting a compiler segmentation fault trying to compile a matrix test
suite. I tried to reduce the test case, but any of a number of ways of
reducing the number of tests that my code does ends up in success. On the
other hand, it doesn't seem to be memory related. The last rsize I saw on top
before it crashed was only 785 MB on a computer with 8GB RAM. So I'm sending
the full preprocessed code that produces the error.
Also, I apologize if this is a duplicate of one of the other "Internal error:
Segmentation fault" reports. But I did look at them, and this doesn't look
like the same thing. At least it's not obviously the same.
Now the particulars:
