Jonathan Keane updated ARROW-14839:
-----------------------------------
Description:
[A recent build
failure|https://dev.azure.com/ursacomputing/crossbow/_build/results?buildId=16168&view=logs&j=0da5d1d9-276d-5173-c4c4-9d4d4ed14fdb&t=d9b15392-e4ce-5e4c-0c8c-b69645229181&l=12205]
We could consider mentioning this upstream to the snappy project. They
[explicitly support
clang|https://github.com/google/snappy/blob/master/CONTRIBUTING.md] clang. I
have confirmed (locally, by setting {{ARROW_VERBOSE_THIRDPARTY_BUILD=ON}} that
snapy 1.1.9 definitely is being installed (which we bumped in ARROW-14594).
We might also try building with the master branch of snappy (which can be
accomplished by changing
https://github.com/apache/arrow/blob/master/cpp/thirdparty/versions.txt#L80-L81
to point to the master branch tar.gz.
