Description

The test is fairly new and has only been run 4 times. It passed the first 3, until 2021/01/14, and failed today, 2021/01/21. See the test history.

Test output:

43: [ RUN      ] AudioDecoder.CheerFile
43: [Err] [C:\Jenkins\workspace\ignition_common-ci-ign-common3-windows7-amd64\ws\ign-common\av\src\AudioDecoder.cc:192] Unable to open audio file[_bad_audio_filename_.wav]
43: [Err] [C:\Jenkins\workspace\ignition_common-ci-ign-common3-windows7-amd64\ws\ign-common\av\src\AudioDecoder.cc:192] Unable to open audio file[C:/Jenkins/workspace/ignition_common-ci-ign-common3-windows7-amd64/ws/ign-common/test\data\audio_bad_codec.grf]
43: [Err] [C:\Jenkins\workspace\ignition_common-ci-ign-common3-windows7-amd64\ws\ign-common\av\src\AudioDecoder.cc:234] Couldn't find audio stream.
43: unknown file: error: SEH exception with code 0xc0000005 thrown in the test body.
43: [  FAILED  ] AudioDecoder.CheerFile (1177 ms)

I've seen this SEH exception on other builds before, so it could be some infrastructure issue.

Contributor guide

Research direction
Investigate the SEH exception (0xc0000005) on Windows in the AudioDecoder.CheerFile test. Check if the issue is caused by a recent code change, an infrastructure problem, or missing audio files. Reproduce the test locally on Windows and trace the error path in AudioDecoder.cc. Look at the test history and linked infrastructure issue for clues.
