Not automated, unfortunately. There is instrumentation built into the
compiler for time taken and memory consumed, which could be used for
automated tests, but DejaGNU is too inflexible.

Which doesn't in the slightest change the value of what you're

Most memory allocation goes through APR pools, so instrument them
somehow; have a command line switch to dump allocation statistics.
