Description Florian Weimer 2017-08-30 11:18:20 UTC
This can lead to permanent loss of NSS functionality in a process:

  https://sourceware.org/ml/libc-alpha/2017-08/msg00206.html

This is another potential root cause for the failure reported in bug 20532.

Dealing with dlopen failures requires proper failure detection and a new (internal) interface; see bug 22040.
