[GitHub] [trafficserver] traeak opened a new issue #8775: test_Alternate_S_to_L_remove_S and test_Alternate_S_to_L_remove_L core dump

[GitBox <gi...@apache.org>]

traeak opened a new issue #8775:
URL: https://github.com/apache/trafficserver/issues/8775


   Found this while performing internal builds for ats92.  Tracked this to PR #8718 which switched some tests from EXPENSIVE to normal.  Verified the dumps on master.
   
   This only happened when doing a fresh build with make -j check.  Running the tests individually worked fine (no mem fault errors).
   
   ```
   ../../build/_aux/test-driver: line 95:  5471 Aborted                 (core dumped) "$@" > $log_file 2>&1
   FAIL: test_Alternate_S_to_L_remove_S
   PASS: test_Alternate_L_to_S_remove_L
   ../../build/_aux/test-driver: line 95:  5474 Segmentation fault      (core dumped) "$@" > $log_file 2>&1
   FAIL: test_Alternate_S_to_L_remove_L
   ```
   
   The best I have for this is from backtrace (no symbols):
   
   ```
