commit 5abeb0edf8903edac402d2fe2f13fa92d65ef6a6 Author: Brian Neradt <[email protected]> AuthorDate: Tue Apr 23 18:34:09 2024 -0500 lsan suppression files for ImageMagic plugins (#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: ================================================================= ==18362==ERROR: LeakSanitizer: detected memory leaks Direct leak of 96 byte(s)
