Comment (by Jigsaw52):
I believe I am experiencing the same issue, with the master branch, on
Ubuntu 18.04 64bits, which uses libc 2.27.
I can confirm the string is being interned correctly: I have checked the
pointers on the sandbox initialization and on the failing syscall and they
are the same.
I have tor run under strace and greped for openat calls and noticed
something: the openat call that kills tor has and extra argument which all
the others do not.
I believe the cause of this problem could be related to this.
I have attached my logs and my orconfig.h file.
