What steps will reproduce the bug?

1. npm install @formatjs/icu-messageformat-parser@3.5.11.
2. Save this script:

try {
  require('@formatjs/icu-messageformat-parser').parse(
    `{0, plural, one {#  ''אהבתי'''} two {# ''אהבתי'''} other {# ''אהבתי'''} }`,
    { requiresOtherClause: true, ignoreTag: true, shouldParseSkeletons: false },
  );
} catch (err) {
  console.error(err);
}

3. Run it. Observe error in the title:

λ node foo.js
node:internal/util/inspect:1885
    tempLine += ctx.stylize(nodeModule, 'module');
                    ^

    at Object.<anonymous> (/Users/ikerins/web/foo.js:7:11)

Node.js v26.3.1

I was not able to reduce the reproduction to not use the library, e.g. by manually constructing a SyntaxError with the same properties that it is producing:
https://github.com/formatjs/formatjs/blob/2093ca683a08dd8ae0226085329e9811eca38791/packages/icu-messageformat-parser/index.ts#L49-L56

I'm not sure why that doesn't work. Sorry.

How often does it reproduce? Is there a required condition?

Always reproduces with the above script. I could not narrow it down beyond that.

What is the expected behavior? Why is that the expected behavior?

console.error does not throw.

What do you see instead?

λ node foo.js
node:internal/util/inspect:1885
    tempLine += ctx.stylize(nodeModule, 'module');
                    ^

Additional information

The SyntaxError being logged looks like this, but just constructing one with these properties directly does not reproduce, for reasons unknown. This:

  console.log(err.message);
  console.log(err.stack);
  console.log(err.location);
  console.log(err.originalMessage);

Produces:

EXPECT_ARGUMENT_CLOSING_BRACE

  end: { offset: 73, line: 1, column: 74 }
}
{0, plural, one {#  ''אהבתי'''} two {# ''אהבתי'''} other {# ''אהבתי'''} }

Also, the offending console.error invocation hangs for a pretty long time before throwing. About 5-7s.
