Issues appear to have occurred in this same area in the past. #3067

Some extra info.

Original source

#!/usr/bin/env node
import "source-map-support/register.js";
async function main() {
}
main();

What is passed into findFirstLineBreakOutsideComment

#!/usr/bin/env node

[Silic0nS0ldier]

It is possible to workaround this by changing the import, which presumably alters the string given to findFirstLineBreakOutsideComment.

e.g.

#!/usr/bin/env node
async function main() {
    await import("source-map-support/register.js");
}
main();
