Control: tag -1 +moreinfo I have tried exactly the same patch half a year ago, which resulted a massive number of segmentation faults. Build log can be found in our buildd.
See https://github.com/oneapi-src/oneTBB/issues/777 I'm not sure whether the latest assembly code in https://github.com/oneapi-src/oneTBB/pull/983 would avoid those segfaults, so tagging this bug with moreinfo.
