Simplified the testcase further, and this looks quite serious. In testcase below, one zero less does not cause the same assert.

Seems to happen whenever sort buffer is set to a value larger than available memory. Unclear why it happens in 10.7 only, which is a bit concerning imho.
in 10.6 MEM_ROOT's block size was size_t, so the problem is only for 10.7.
Issue remains in 10.7 as of 15-09-21
block_size <= 0xFFFFFFFFL|SIGABRT|calculate_block_sizes|init_alloc_root|init_tree|Unique::UniqueI agree this is likely critical.
