Well, DOES _G['tonumber'] exist? If it would evaluate falsy, then that
WOULD return assert.

`assert` would be fine with a string (or *any* value for that matter) as the second argument since the first argument is true-ish. So it really is `tonumber` throwing the error ...

The problem seems to be that the debug code figuring out a name for the called function gets confused by `(_G and tonumber or assert)`.

Error occurs in both 5.1.5 and 5.2.2.
