Getting rid of ERR does not help, because this if ((send...) < 0) condition is never fulfilled. It looks like send() kills program. It sounds crazy.
I have put my whole code on github: https://github.com/chelmsford/Scrabble
Maybe you will find something what I can't see.

LIBXO(3)						   BSD Library Functions Manual 						  LIBXO(3)

NAME
xo_emit -- emit formatted output based on format string and arguments LIBRARY
library ``libxo'' SYNOPSIS
#include <libxo/xo.h> int xo_emit(const char *fmt, ...); int xo_emit_h(xo_handle_t *xop, const char *fmt, ...); int xo_emit_hv(xo_handle_t *xop, const char *fmt, va_list vap); DESCRIPTION
The xo_emit() function emits formatted output using the description in a format string along with a set of zero or more arguments, in a style similar to printf(3) but using a more complex format description string, as described in xo_format(5). xo_emit() uses the default output handle, as described in libxo(3), where xo_emit_h() uses an explicit handle. xo_emit_hv() accepts a va_list for additional flexibility. ADDITIONAL DOCUMENTATION
Complete documentation can be found on github: http://juniper.github.io/libxo/libxo-manual.html libxo lives on github as: https://github.com/Juniper/libxo The latest release of libxo is available at: https://github.com/Juniper/libxo/releases SEE ALSO
xo_open_container(3), xo_open_list(3), xo_format(5) HISTORY
