Comment (by ageisp0lis):

 >
 > Question 1: Can you tell me, what version of libc exactly does your
 system use?  I am wondering if maybe we have a problem in our
 implementation of libc_uses_openat_for_everything, which checks for a
 version later than 2.26.

 Thought I had replied to you already but didn't see it on the ticket!
 Oops. Pretty sure I was using 2.27.

 >
 > Question 2: And if you're building Tor from source, could you attach the
 orconfig.h file that is generated when you run "configure" to build tor?

 Was running official binaries from your apt repository, in the 'buster'
 distribution, not built from source.
