> 11 corresponds to `math_node` in LuaTeX (according to `texnodes.h` line 412). This error message comes from the `synctexhorizontalruleorglue` function, when it is called on a node with the wrong type. It means that `synctexhorizontalruleorglue` is called on a math node, which is not expected. So, somewhere in LuaTeX, `synctexhorizontalruleorglue` is used instead of the dedicated `synctexmath`. Also, the problem is somehow related to `\mathsurroundskip`.

because in that case the mathnode *is* a glue node, that is: it's glue 
fields are used (and they have the same layout as a glue node) so 
synctex should just accept a math node as valid glue in luatex
