flaky SIGBUS on ubuntu github action runner #116

Closed MichaelBelousov closed 11 months ago

MichaelBelousov commented 1 year ago

Describe the bug At an undetermined time while starting up an application that loads iTwin.js backend code (the imodel-transformer tests) on ubuntu github runners, randomly a SIGBUS occurs. So far has occurred 3 times out of maybe 8 runs since we added 4.x support tests

To Reproduce Steps to reproduce the behavior:

Run iModel Transformer CI: https://github.com/iTwin/imodel-transformer/actions/runs/5221816350/jobs/9426561235?pr=60

Expected behavior No SIGBUS, tests startup (mocha should run through all the imports and test initialization and then print the content of the Catalog tests's describe label.

Screenshots

packages/transformer test: Bus error (core dumped)
packages/transformer test: Failed
undefined

Desktop (please complete the applicable information):

Additional context

Perhaps the best way to debug this is turn on core dumping and upload that somewhere

Closing as I can't reproduce. After seeing it 3 times randomly, I modified CI to run the tests during which it occurred, 100 times normally, 100 times under gdb -batch to try to print stacktrace. Neither caught it.

maybe my CI test was somehow flawed, it appears with some regularity in other transformer CI builds

haven't seen this in forever, closing
