#39: Memory leak at exit --------------------------------+------------------------------------------- Reporter: gcdanie@… | Type: defect Status: new | Priority: don't know Component: don't know | Version: git repository Keywords: | --------------------------------+------------------------------------------- When using aethread, some memory is not freed at exit (example below is from the aefile-example, but is reproducible by any aethread using program). Fortunately, the amount of reachable memory seems to be fixed regardless of how often aethreads are used (verified in aefile-example.ae by running the tests twice in the main loop). ==31478== HEAP SUMMARY: ==31478== in use at exit: 440 bytes in 2 blocks ==31478== total heap usage: 70 allocs, 68 frees, 101,172 bytes allocated ==31478== ==31478== Thread 1: ==31478== 168 bytes in 1 blocks are still reachable in loss record 1 of 2 ==31478== at 0x4C28BED: malloc (vg_replace_malloc.c:263) ==31478== by 0x40728F: aethread_create_group_pool (aethread.c:89) ==31478== by 0x4044E7: aefile_init (aefile.ae:39) ==31478== by 0x403F4F: __ae_worker_aesop_main (in /home/jehannum/Source /aesop-test/aefile-example) ==31478== by 0x4041D1: aesop_main (in /home/jehannum/Source/aesop-test /aefile-example) ==31478== by 0x404436: main (in /home/jehannum/Source/aesop-test /aefile-example) ==31478== ==31478== 272 bytes in 1 blocks are possibly lost in loss record 2 of 2 ==31478== at 0x4C272B8: calloc (vg_replace_malloc.c:566) ==31478== by 0x401128E: _dl_allocate_tls (dl-tls.c:300) ==31478== by 0x4E36483: pthread_create@@GLIBC_2.2.5 (allocatestack.c:580) ==31478== by 0x40732D: aethread_create_group_pool (aethread.c:111) ==31478== by 0x4044E7: aefile_init (aefile.ae:39) ==31478== by 0x403F4F: __ae_worker_aesop_main (in /home/jehannum/Source /aesop-test/aefile-example) ==31478== by 0x4041D1: aesop_main (in /home/jehannum/Source/aesop-test /aefile-example) ==31478== by 0x404436: main (in /home/jehannum/Source/aesop-test /aefile-example) ==31478== ==31478== LEAK SUMMARY: ==31478== definitely lost: 0 bytes in 0 blocks ==31478== indirectly lost: 0 bytes in 0 blocks ==31478== possibly lost: 272 bytes in 1 blocks ==31478== still reachable: 168 bytes in 1 blocks ==31478== suppressed: 0 bytes in 0 blocks ==31478== ==31478== For counts of detected and suppressed errors, rerun with: -v ==31478== Use --track-origins=yes to see where uninitialised values come from ==31478== ERROR SUMMARY: 2 errors from 2 contexts (suppressed: 4 from 4) -- Ticket URL: <http://trac.mcs.anl.gov/projects/aesop/ticket/39> aesop <https://trac.mcs.anl.gov/projects/aesop> The Aesop Language
