[Bug-wget] wget 1.17 segfaults under openSUSE 13.1 (x86_64; glibc 2.18)

[Schleusener, Jens]

Hi,

under some conditions I get with a self-compiled wget 1.17 binary on a 
64-bit openSUSE 13.1 Linux system a segmentation fault (but the 
self-compiled wget 1.16.3 works correctly).

I could reduce the problem to this usage case:

 wget -N --content-disposition http://ftp.gnu.org/gnu/wget/

while the usage of only "-N" or "--content-disposition" let wget work.

Sorry, I am not a C expert but nevertheless I tried to use gdb on the 
resulting core dump as best I could with the following result:

 Program terminated with signal SIGSEGV, Segmentation fault.
 #0  0x00007f5b0899d42a in strlen () from /lib64/libc.so.6
 (gdb) bt
 #0  0x00007f5b0899d42a in strlen () from /lib64/libc.so.6

 #3  0x0000000000433619 in retrieve_url ()
 #4  0x000000000042c64b in main ()

The used gcc version is
 4.8.1
and a "rpm -qf /lib64/libc.so.6" issues
 glibc-2.18-4.38.1.x86_64

On a newer openSUSE Leap 42.1 Linux system the "identically" compiled wget 
doesn't segfault and works ok. On that system the gcc version is
 4.8.5
and a "rpm -qf /lib64/libc.so.6" issues
 glibc-2.19-17.4.x86_64
