sockaddr might be null or has been overwritten and is pointing to some odd location.
Won't matter in this case:
The sockaddr isn't an address - it's a structure, and the results of the strcpy() depend on long argv[1] is. It could segv, or not.
Now, the content of sa_data is almost certainly not expected to be in string format, though....

ipsec_portof
IPSEC_PORTOF(3) Library Functions Manual IPSEC_PORTOF(3)NAME
ipsec_portof, ipsec_setportof, ipsec_sockaddrof, ipsec_sockaddrlenof - get port field of an ip_address, set port field of an ip_address,
get pointer to internal sockaddr of an ip_address, get length of internal sockaddr of an ip_address
SYNOPSIS
#include <freeswan.h>
int portof(const ip_address *src);
void setportof(int port, ip_address *dst);
struct sockaddr *sockaddrof(ip_address *src);
size_t sockaddrlenof(const ip_address *src);
DESCRIPTION
The <freeswan.h> internal type ip_address contains one of the sockaddr types internally. Reliance on this feature is discouraged, but it
may occasionally be necessary. These functions provide low-level tools for this purpose.
Portof and setportof respectively read and write the port-number field of the internal sockaddr. The values are in network byte order.
Sockaddrof returns a pointer to the internal sockaddr, for passing to other functions.
Sockaddrlenof reports the size of the internal sockaddr, for use in storage allocation.
SEE ALSO inet(3), ipsec_initaddr(3)DIAGNOSTICS
Portof returns -1, sockaddrof returns NULL, and sockaddrlenof returns 0 if an unknown address family is found within the ip_address.
HISTORY
Written for the FreeS/WAN project by Henry Spencer.
BUGS
These functions all depend on low-level details of the ip_address type, which are in principle subject to change. Avoid using them unless
really necessary.
