Modify the {{examples/c/proactor/receive.c}} with the attached patch. Then build and run like this {noformat} $ nc -l 5672 < leak-f1c681da874efe3b168d6bd00e1de53c5a3823ea $ valgrind --leak-check=full ./libuv_receive -a 127.0.0.1:5672/jms.queue.example ==19440== Memcheck, a memory error detector ==19440== Copyright (C) 2002-2015, and GNU GPL'd, by Julian Seward et al. ==19440== Using Valgrind-3.12.0 and LibVEX; rerun with -h for copyright info ==19440== Command: ./libuv_receive -a 127.0.0.1:5672/jms.queue.example ==19440== ==19440== ==19440== HEAP SUMMARY: ==19440== in use at exit: 67,206 bytes in 452 blocks ==19440== total heap usage: 470 allocs, 18 frees, 72,587 bytes allocated ==19440== ==19440== 67,206 (288 direct, 66,918 indirect) bytes in 1 blocks are definitely lost in loss record 450 of 450 ==19440== at 0x4C2CA40: calloc (in /usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so) ==19440== by 0x4E50E4E: pn_object_new (object.c:202) ==19440== by 0x4E51160: pn_class_new (object.c:61) ==19440== by 0x4E6310A: pn_connection (engine.c:514) ==19440== by 0x4043B0: main (receive.c:203) ==19440== ==19440== LEAK SUMMARY: ==19440== definitely lost: 288 bytes in 1 blocks ==19440== indirectly lost: 66,918 bytes in 451 blocks ==19440== possibly lost: 0 bytes in 0 blocks ==19440== still reachable: 0 bytes in 0 blocks ==19440== suppressed: 0 bytes in 0 blocks ==19440== ==19440== For counts of detected and suppressed errors, rerun with: -v ==19440== ERROR SUMMARY: 1 errors from 1 contexts (suppressed: 0 from 0) {noformat} Log from when I enabled AddressSanitizer instead of Valgrind is in attachment.
