We hit a test failure on Windows too: (from https://logs.chromium.org/logs/chromium/buildbucket/cr-buildbucket/8739447000055620209/+/u/package_clang/stdout)

Note that `long` is 32 bits on Windows, but this is a 64-bit build, so size_t should be 64 bits.

... and now I see there's fix in 14d57e21e1cc76de554314015e11a9d6e9b797f5, that should work for us too.
