Subject: http_send.c: Fix a bug in http_post_select().
X-Git-Tag: v0.3.1~49
X-Git-Url: http://git.tuebingen.mpg.de/?p=paraslash.git;a=commitdiff_plain;h=3ac7a00c79a39801f497b48385dae580a08c3cf8;hp=2b4a72bab701de1add388f89a92f1b7a358dab79

http_send.c: Fix a bug in http_post_select().

If the accept() on the listen_fd fails, we don't have a valid
file descriptor but tried to close it anyway. Even worse, the
old code dereferenced and then freed the "sc" pointer which
isn't inititialized at that point.
