Subject: Check for invalid COMSTACK addresses
X-Git-Tag: v4.2.9~3
X-Git-Url: http://git.indexdata.com/?p=yaz-moved-to-github.git;a=commitdiff_plain;h=d1f18e923658fe9817fbda7b510ae40e9be69e7f

Check for invalid COMSTACK addresses

Check return value of cs_parse_host in cs_create_host_proxy. For
example, yaz-url would SEGV if ssl/https was given and SSL was
not enabled in the built (as it happens on Windows).
