Maybe this failure with a newly built gcc 4.8 is related to this bug.
Built gcc today from

gcc version 4.8.2 20130920 (prerelease) (GCC)
Compiling the following simple program with these options on an Ubuntu 12.04
causes a failure:
$ gcc -Wp,-D_FORTIFY_SOURCE=2 -O2 -D_GNU_SOURCE=1
-- foo.c --
#include <sys/socket.h>
extern ssize_t recvfrom(int s, void *buf, size_t len, int flags, struct
sockaddr *from, socklen_t *fromlen);
int main()
{
int s, flags; void *buf; size_t len; struct sockaddr *from; socklen_t*
fromlen;
return(recvfrom(s, buf, len, flags, from, fromlen));
}
-- foo.c --
~/gcc48/bin$ ./gcc -Wp,-D_FORTIFY_SOURCE=2 -O2 -D_GNU_SOURCE=1 foo.c
