Subject: Fix problem with pointer to last init response being corrupt
X-Git-Tag: YAZXF2.1.4.2.2.release~35
X-Git-Url: http://sru.miketaylor.org.uk/cgi-bin?a=commitdiff_plain;h=71664fe63983cbd1a74e22dd2f5fb75df2f57981;p=yaz-moved-to-github.git

Fix problem with pointer to last init response being corrupt
due to set_auto_wait=off. If we have not yet received init response
we assume option is set.
