What steps will reproduce the bug?
npm install @formatjs/icu-messageformat-parser@3.5.11.- 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);
}- Run it. Observe error in the title:
λ node foo.js
node:internal/util/inspect:1885
tempLine += ctx.stylize(nodeModule, 'module');

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
SyntaxError: EXPECT_ARGUMENT_CLOSING_BRACE

}
{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.
