Nondeterministic line number in error reporting for RangeError message #1758
Description
test('Simple arrow function infinite recursion represents CallExpression well', () => {
return expectParsedError('(x => x(x)(x))(x => x(x)(x));').toMatchInlineSnapshot(
`"Line 1: RangeError: Maximum call stack size exceeded"`
)
}, 30000)
test('Simple function infinite recursion represents CallExpression well', () => {
return expectParsedError('function f(x) {return x(x)(x);} f(f);').toMatchInlineSnapshot(
`"RangeError: Maximum call stack size exceeded"`
)
}, 30000)
I refer to these 2 testcases in src/__tests__/index.ts. Developers have noted that the first test case seems to have non-determinstic behaviour, sometimes showing the line number and sometimes not - this is due to the line number sometimes showing as -1 instead of 1. We have currently pushed a stop-gap fix to this issue.
Additionally, it is strange that both test cases result in different error messages.
