New Revision: 362354
URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=362354
Log:
Make use of va_args more appropriate to form in various res_config modules plus utils.
A number of va_copy operations weren't matched with a corresponding va_end in res_config_odbc. Also, there was a potential for va_end to be invoked twice on the same va_arg in utils, which would mean invoking va_end on an undefined variable... which is bad.
va_end is removed from various functions in config_pgsql and config_curl since they aren't making their own copy. The invokers of those functions are responsible for calling va_end on them.
(closes issue ASTERISK-19451)
