I get my final “done” message with valgrind, and get this exit report:

==3434== HEAP SUMMARY:
==3434==     in use at exit: 8,432 bytes in 4 blocks
==3434==   total heap usage: 4,369 allocs, 8,037 frees, 377,356 bytes allocated
==3434== 
==3434== LEAK SUMMARY:
==3434==    definitely lost: 152 bytes in 1 blocks
==3434==    indirectly lost: 0 bytes in 0 blocks
==3434==      possibly lost: 0 bytes in 0 blocks
==3434==    still reachable: 8,192 bytes in 2 blocks
==3434==         suppressed: 88 bytes in 1 blocks
==3434== Rerun with --leak-check=full to see details of leaked memory
==3434== 
==3434== For counts of detected and suppressed errors, rerun with: -v
==3434== ERROR SUMMARY: 100190 errors from 140 contexts (suppressed: 0 from 0)

But when I run it without valgrind, it segfaults immediately. Does valgrind suppress a certain kind of error that I should be looking for? I can’t find any information about this online

    Valgrind runs the program in a different environment than if you run it from the shell.
    This can prevent some crashes when relative to memory exhaustion or array outbounding.

    Correct your 140 contexts of errors and you’ll be okay.
