The issue was caused by misplacement of allocated blocks in rbtree due to broken comparison function if the distance between two allocations did not fit into intptr_t. As the result, nxt_mp_free() could have failed to find the allocation. In particular, it was mostly observed when Unit was compiled with musl C library on 32-bits systems. This closes #118 issue on GitHub.
