Shadow for this rangeoverlaps with shadow for other user regions.This causes havok: from false positives to crashes.Don't leave unmapped holes in the traces region.Reviewed-in: https://reviews.llvm.org/D96697 List of files: /llvm-project-15.0.7/compiler-rt/test/tsan/mmap_lots.cpp Mon, 15 Feb 2021 10:25:48 +0000 Dmitry Vyukov <dvyukov@google.com>
