The shell behaviour does not change for --trace-children=yes/no. But when giving --trace-children=yes, you should get additional input before. E.g. this is what I get: ==3589== Command: ./run.sh ... ==3590== Command: /home/philippe/valgrind/trunk_untouched/memcheck/tests/trivialleak ... ==3590== HEAP SUMMARY: ==3590== in use at exit: 1,000 bytes in 1,000 blocks ==3590== total heap usage: 1,000 allocs, 0 frees, 1,000 bytes allocated ... ==3589== HEAP SUMMARY: ==3589== in use at exit: 19,960 bytes in 572 blocks ==3589== total heap usage: 725 allocs, 153 frees, 26,630 bytes allocated ... So, with trace children, you see lines for different pids (and a heap summary result for each process which exits) Philippe ------------------------------------------------------------------------------ CenturyLink Cloud: The Leader in Enterprise Cloud Services.
