I'm posting a snippet I use to convert the obscure exceptions messages when
exception handling is disabled to a string value. Since this relies on
re-entering the Emscripten environment after its in a bad state, it's
possible that some exceptions can't be dumped this way, but for those that
return simple strings, it should work.
It works by looking up the 'what' function in the exceptions vtable.
function whatEmscriptenException(ptr) {
// 8 should be the vtable offset for the what function
var fPtr = Module.HEAPU32[(Module.HEAPU32[(ptr) >> 2] + 8) >> 2];
console.info(Module.AsciiToString(Module.dynCall_ii(fPtr, ptr)));
}
