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

#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

Jens
