It's a pCloud issue. pCloud defines __has_builtin(x) to 1 here:

https://github.com/pcloudcom/console-client/blob/cd02e53e0d0f2884c5742899c84874dffa528834/pCloudCC/lib/pclsync/pcompiler.h#L50

which then makes Boost think that __builtin_assume is supported, and it 
isn't. Similarly for __builtin_addressof.
