[PATCH] Remove possible segfault in http-fetch.

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Free the curl string lists after running http_cleanup to
avoid an occasional segfault in the curl library.  Seems
to only occur if the website returns a 405 error.

Florian, could you please test this patch.

It comes with a big disclaimer because I don't really know the
code in here all that well.  However gdb reports the segfault
happens in a strncasecmp call, and seeing as we've released a
bunch of strings prior to the call....

Testing seems to confirm that the segfault is removed by this patch.

As to why the website returns a 405 error in the first place is still
a mystery to me.
