Subject: [PATCH 69/75] Ticket 48311 - nunc-stans: Attempt to release
connection that is not acquired
Bug Description: ns_connection_post_io_or_closing() was not aquiring the
connection in the optimized build, which led to the connection
ref count getting out sequence.
Fix Description Do not call connection_acquire_nolock() inside a PR_ASSERT call.
Also changed other PR_ASSERTs to only be called if DEBUG is set
