I found I could get similar errors in the help window, for example by
binding 'H' to something else in .infokey and running "M-x 
get-help-window".  The replace_in_documentation didn't check for
buffer overflow everywhere it should have.  (It did in one place,
but it wasn't enough.)  I've made changes to keep track of the size
of the buffer size properly.
