Test case

This test case instantiates __mt_alloc on 1024 different types. It uses about
300 MB of memory, almost all of which is overhead (any memory allocated from
__mt_alloc is deallocated before any more memory is requested). The thread
stuff is just to force __gthread_active_p() to return true.

WARNING: Compiling this takes huge amounts of time and memory.
