It sets MALLOC_PERTURB_=69 in the environment, so the allocated memory is initialized to 0xba. Later in io_uring_get_sqe() -> _io_uring_get_sqe(): 1424 if (next - head <= sq->ring_entries) { (gdb) p *sq $2 = {khead = 0x55555555d000, ktail = 0x55555555d004, kring_mask = 0x55555555d010, kring_entries = 0x55555555d018, kflags = 0x55555555d024, kdropped = 0x55555555d020, array = 0x0, sqes = 0x55555555c000, sqe_head = 0, sqe_tail = 0, ring_sz = 0, ring_ptr = 0x55555555d000, ring_mask = 0, ring_entries = 1, pad = {0, 0}} (gdb) p sq->ring_entries $3 = 1 (gdb) p next $4 = 1 (gdb) p/x head $6 = 0xbabababa And that causes a crash, of course. Fix that by zeroing the memory after posix_memalign().
