Reproduce the OpenEXR 3.1.7 build on armv7l-linux from the linked build log, then run the failing CTest cases OpenEXR.testMultiTiledPartThreading and OpenEXR.testRgbaThreading. Inspect the related threading paths and the mentioned sources, including src/lib/OpenEXR/ImfFastHuf.cpp and ImfTileOffsets.cpp. Done means both tests complete without segmentation faults on the affected platform.
