Hi, all,
The followings are some bugs found by our static analysis tool bugprobe in 
In file recur.c
At line 281, function url_parse may return NULL assigned to url_parsed.
Function retrieve_url use url_parsed without null check.

All program points that call function url_parse also exist this kind of bugs.

In file warc.c
At line 734, newly allocated memory assigned to new_filename may be null.

And some comparisons with '==' between double values.

I wonder if these are real bugs.
Thank you!
