The issue seems to be caused by a bug in ASan, as reported\nin https://github.com/google/sanitizers/issues/934, which is triggered\nwhen dynamically loading a .so module in conjunction with a libasan\nimplementation linked with --as-needed. This causes a failure to\nproperly handle exceptions.\n\nPatch 1/2 is a small improvement for the Python unit test meson.build\nfile, to prepare for patch 2/2 that then works around the issue by\nLD_PRELOAD'ing the C++ standard library.\n\nThe series doesn't break CI\n(https://gitlab.freedesktop.org/camera/libcamera/-/pipelines/1304028)\nand fixes the issue on my machine with gcc 9 to 14, using libstdc++.\nclang with libc++ is still broken, waiting for a volunteer to fix it :-)\n\nLaurent Pinchart (2):\n test: py: Replace environment array with environment object\n test: py: LD_PRELOAD the C++ standard library when using ASan\n\n meson.build | 3 +++\n test/py/meson.build | 14 ++++++++++++--\n 2 files changed, 15 insertions(+), 2 deletions(-)\n\n\nbase-commit: f028b09b7becf4e7847112b2e8044e5e30e01c58"}
