I don' think there's any way the browser can distinguish these two
cases, even if source maps could be changed to help.

If your translator correctly preserves the meaning of the program you
translated, and your program doesn't have a bug, it shouldn't crash.

If your program is correct, but the translated code crashes, that is, by
definition, a bug in the translator.

Am I missing something?
