Description Dimitry Andric freebsd_committer 2016-02-14 22:01:10 UTC
During a recent exp-run for bug 206074, it was found that www/uwsgi gives errors with clang 3.8.0 [1]:

/cgi_plugin.c:771:3: error: variable 'i' is incremented both in the loop header and in the loop body [-Werror,-Wfor-loop-analysis]
plugins/cgi/cgi_plugin.c:766:30: note: incremented here
        for(i=0;i<wsgi_req->var_cnt;i++) {

This new clang warning normally indicates some bug, but in this case upstream fixed it by explicitly increasing the counter by two. [2]
