[Question] [HW4] How do SendError and RecvError occur at the same time? about cs431 HOT 6 CLOSED

It looks strange to me, too. Does the same thing happen in the provided testcases (e.g. by running grade-boc.sh)?

from cs431.

By running, grade-boc.sh, this error occured in both basic test and stress test:

error: test failed, to rerun pass `--test boc`

Caused by:
  process didn't exit successfully: `C:\Users\KoWH\cs431\homework\target\debug\deps\boc-ce57516ad9d8cba7.exe basic_test` (exit 
code: 0xc0000005, STATUS_ACCESS_VIOLATION)
note: test exited abnormally; to see the full output pass --nocapture to the harness.
Test failed:    cargo test  --test boc basic_test

I found STATUS_HEAP_CORRUPTION error occurs immediately after the end of one Behaviour. But I don't know why.

I am having the exact same problem. Getting errors like this, and every time a different one.

@kowonhyeok @SaschaBergsma STATUS_ACCESS_VIOLATION and STATUS_HEAP_CORRUPTION both tell you that your code has some memory access bugs. I can now guess that you are having such strange errors that SendError and RecvError happen simultaneously since you're corrupting the memory space internally used by crossbeam_channel. I advise you to carefully look at your code if there are any mistakes when storing and accessing the raw pointers.

Thank you! I found my problem is caused by lifetime of Behavior object. This is very helpful: #905.
