You are welcome to submit bug reports via the GNU Wget bug tracker (see https://savannah.gnu.org/bugs/?func=additem&group=wget).
Before actually submitting a bug report, please try to follow a few simple guidelines.
Also, while I will probably be interested to know the contents of your .wgetrc file, just dumping it into the debug message is probably a bad idea. Instead, you should first try to see if the bug repeats with .wgetrc moved out of the way. Only if it turns out that .wgetrc settings affect the bug, mail me the relevant parts of the file.
Note: please make sure to remove any potentially sensitive information
from the debug log before sending it to the bug address. The
-d won’t go out of its way to collect sensitive information,
but the log will contain a fairly complete transcript of Wget’s
communication with the server, which may include passwords and pieces
of downloaded data. Since the bug address is publically archived, you
may assume that all bug reports are visible to the public.
gdb `which wget` coreand type
whereto get the backtrace. This may not work if the system administrator has disabled core files, but it is safe to try.
