Bug description: Segfault in function php_curl_option_url
Description:
------------
There is segfault in strncasecmp calling from this code:
curl/interface.c:186 :
if (!strncasecmp("file", uri->scheme, sizeof("file"))) {
...
when URI is without protocol part hence uri->scheme is NULL.
Like in this example of backtrace:
#0 0xb7e20a8b in strncasecmp () from /lib/i686/cmov/libc.so.6
#1 0xb777dd11 in php_curl_option_url (ch=0x856be00,
url=0x856e360
"show.setlinks.ru/?host=SCREENEDHOSTNAME&k=WINDOWS-1251&p=b44eff595164745dee4a6a655a57a425",
