From: Sunil Dora <[email protected]> clang 23's lifetime analysis flags the framework's postprocessing_computepass.cpp taking .begin() of a temporary, and the project builds with -Werror:
framework/rendering/postprocessing_computepass.cpp:154:33: error: object backing the pointer will be destroyed at the end of the full-expression [-Werror,-Wdangling-gsl] The warning is a true positive: get_resources() returns a vector by value, so the code compares iterators from two different temporaries and later dereferences a dangling one. The affected class is unused (Vulkan-Samples issue #841) but still compiled everywhere. Reported upstream with analysis and a proposed fix: https://github.com/KhronosGroup/Vulkan-Samples/issues/1570 Fixing the framework source is upstream's call; from the recipe, extend the existing clang workaround flags to keep the warning non-fatal.
