Yeah it's definitely not the same problem, I don't even use boost.
And I only have this 3 errors in a million line project, the project is 
against libc++ wich is default in NDK 17.
If it was the same issue, I'd probably get thousands of similar errors.

Yeah I suspected a similar issue, until now I couldn't figure out what's 
causing it.
Googling didn't help so far.
I removed all my libs again and rebuilt everything from scratch and 
still get this, so I'm a bit puzzled.

Anyway thanks for your thoughts so far.
