Certain tests (many are from lld/test) run `... '2>&1 | count 0` to ensure that there is no stderr message. GetRegistersAndSP may rarely fail, leading to a spurious failure like (with a local hack to make `count` dump the input): ``` + /home/ray/llvm/out/asan/bin/ld.lld func1-gcs.o func2-gcs.o func3-gcs.o -o /dev/null -z gcs-report=warning -z gcs=never + /home/ray/llvm/out/asan/bin/count 0 Expected 0 lines, got 1. ==2403039==Unable to get registers from thread 2403018. ``` The failure can reliably be reproduced by running `ninja check-lld` a few times under asan+lsan (see the bot sanitizer-x86_64-linux-bootstrap-asan).
