Could not find key in given stack trace lines

When I try running a build and test according to the README, but on my own project, I get the following error:

[16.091s] ERROR:colcon.colcon_core.event_reactor:Exception in event handler extension 'sanitizer_report': Could not find key in given stack trace lines.

AssertionError: Could not find key in given stack trace lines.

Do my tests need special instrumentation to support this?
