This is because the program has exited. X protocol error messages
are displayed by using glibc's printf and friends, so you could
just insert breakpoints to printf and fprintf.

This may be annoying. When I build with '--with-x-toolkit=lucid
--without-toolkit-scroll-bars --without-gconf --without-gsettings',
resulting binary depends on 92 libraries:

So if we have a glitch with some external library, there are 66 libraries
under suspicion. An idea is to remove library dependencies one by one
using --without-XXX option until the problem disappears; if you have
a better approach, it's definitely appreciated.
