Emscripten versions (3.1.34 vs. 3.1.28)

[craigsapp]

I was updating Emscripten emsdk on a computer and I notice that verovio has problems related to an undefined variable/function when running in the latest version (3.1.34), so I switched to the one I am currently using (3.1.28). Is that a known problem (@WolfgangDrescher)? I have seen some discussion probably related to that in the past few months in the verovio issues/discussion

Or is there new Javascript code that is necessary to load verovio with emsdk 3.1.34?

I just updated to emcc v3.1.34 and compiled with buildNpmPackage without any problems. Also using verovio-toolkit-wasm.js worked as expected. What error message do you get? In the JS console or during compilation?
