Crash signature 69f8ebe0f20e.
RivSeismicSectionPartMgr::appendSurfaceIntersectionLines reads texturePart.rect[0] and rect[1] without a size check. texturedSection() clears rect and returns early when the section has no geometry, so the read is out of range.
Skip parts with fewer than two corner points.
