a.out.patch is needed since function pointers were overloaded and emscripten got confused. Without it, this happens:

Invalid function pointer '42' called with signature 'iiii'. Perhaps this is an invalid value (e.g. caused by calling a virtual method on a
NULL pointer)? Or calling a function with an incorrect type, which will fail? (it is worth building your source files with -Werror (warni
ngs are errors), as warnings can indicate undefined behavior which can cause this)
This pointer might make sense in another type signature: iii: asm['_plus'] ii: 0 viii: 0 viiii: undefined vii: 0 vi: 0
