Runaway compiler memory use in test

[Dave Abrahams]

On GCC-4.1.0 just compiling the test_ibeta_real_concept and test_binomial_real_concept tests consume over 1.6G of memory before I decide that the swapping is unacceptable and I kill cc1plus. That leads me to suspect strongly that source:/trunk/status/explicit-failures-markup.xml@48168#L3411 wrongly blames the running time of the test. It seems to me that these tests might be made to work by breaking up the source files into chunks that are manageable by the compiler.

I'm happy to give you access to a system where you can experience the issue firsthand if you don't have one yourself.
