bneradt opened a new pull request, #11282:
URL: https://github.com/apache/trafficserver/pull/11282
ASan reports a leak concerning the ImageMagick library for plugins that link
against it. The leak is associated with the ImageMagick library itself as
commenting everything out from the ATS plugin, leaving a bare TSPluginInit,
still results in the leak report. This patch suppresses the leak report for the
library we do not own and for a leak that has not been seen to be any larger
than the initialization bytes associated with the library.
Here's the leak report this suppression file addresses:
