Package: libtorrent-rasterbar2.0

Severity: grave

Control: notfound -1 2.0.6-3
Dear Maintainer,
bug #1013470 about a nbdkit rebuild failure was reported and it turned
out that this happens because of a crash that happens even in trivial
cases:

>From the output, it looks as if the crash occurred on a cleanup code
path.
Downgrading to 2.0.6-3 (before the OpenSSL 3 rebuild) makes the
segmentation fault go away.
The stacktrace below suggests that this is related to cleanup code
registered using atexit(3): pthread_rwlock_wrlock() is called with a
NULL pointer.
