I added a function that verifies the hash value of glyph rows before
it is used in row_equal_p, and also in adjust_glyph_matrix, where the
offending reallocation takes place.  I cannot trigger the xasserts
that use this function when I use "C-h H".  Can you?

If the hash values are always correct where they are used, I guess
that excludes the possibility that we use an uninitialized value,
right?
