#63 Calling abort() while trying to listen using UDP

[Felipe Cerqueira]

Hello,

It is crashing (calling abort()) using the following syntax:
./netcat -4 -vv -l -u -p 4444

(gdb) set args -4 -vv -l -u -p 4444
(gdb) r
Starting program: /home/sky/netcat-code/src/netcat -4 -vv -l -u -p 4444

Program received signal SIGABRT, Aborted.
0x00007ffff7a4bcc9 in __GI_raise (sig=sig@entry=6) at ../nptl/sysdeps/unix/sysv/linux/raise.c:56
56      ../nptl/sysdeps/unix/sysv/linux/raise.c: No such file or directory.
(gdb) bt

(gdb)

The problem is in netcore.c line 104 where it is using PF_INET while should use the enum nc_domain_t.
Actually, it is happening two times in the code (always for UDP)

I am attaching a patch file ok?

Thanks
