I had an instance of SER crash in production with this error message from qm_debug_frag: [mem/q_malloc.c:149]: BUG: qm_*: fragm. 0x4cee3b88 (address 0x4cee3ba0) end overwritten(0, 0)! The fragment end was been overwritten with zeroes... buffer overflow? Or an aliasing bug? Maybe a double-free? It would be much easier to debug problems like this if qm_debug_frag printed the call site where qm_malloc/free was invoked from. And now it does!
