FYI,

Looking at source code for dvisvgm, this error comes from

  http://tug.org/pipermail/tex-live-commits/2016-July/000342.html


DVIReader.cpp
/** Reads and executes DVI postamble command.
  *  Format: post p[4] num[4] den[4] mag[4] ph[4] pw[4] sd[2] np[2] */
void DVIReader::cmdPost (int) {
....
if (numPages != numberOfPages())
		throw DVIException("page count in postamble doesn't match actual number of pages");
....


The question is why it happens on this Latex file?
