Created attachment 632296 [details, diff] Bug that fixes a format string size problem This fixed a different but related error that I believe FORTIFY_SOURCE caught with snprintf. The string being written to was calloc'd to support the colon, a NULL, the original address string, and an unsigned short (as supported by the sockets API). The format string instead uses a %d. I've attached this patch which fixes the compilation for me.
