Should we also do another print from the catch to make sure it routes that way?

Style: snake_case, not camelCase for parameters (i.e., handling_fatal_error.)
Also, an enum might be nicer because it gives a clear hint what the parameter does at the call site. With bools, I usually use a local variable to make it obvious:
const bool handling_fatal_error = true;
AppendExceptionLine(env, err, message, handling_fatal_error);There was a problem hiding this comment.
Aside: is_fatal_error is a bit more succinct.

I’ve updated with an enum, that’s a good idea.

The enum keyword is not strictly necessary (but it doesn't hurt and I realize we use it in other places.)

LGTM with comments. |

This is the tiniest of nits, but maybe say vm.runInThisContext() should not print anything... As it currently stands, it seems like nothing should be printed at all, or the catch won't print anything either.

@cjihrig Done, forgot to update this along with the catch block

LGTM I suppose. |

@addaleax this is not landing cleanly, would you be willing to backport to v4.x? |
