New issue 4364 by [email protected]: Some of the SyntaxError message
missing when exception rethrown (d8 bug)
https://code.google.com/p/v8/issues/detail?id=4364
Version: V8 version 4.3.61
OS: Mac
Architecture: x86_64
What steps will reproduce the problem?
1. Create a file foo.js with content as follows:
try {
eval('for i in range(10):');
} catch (err) {
throw err;
}
2. d8 foo.js
*What is the expected output?
undefined:1: SyntaxError: Unexpected identifier
for i in range(10):
^
SyntaxError: Unexpected identifier
at test.js:2:1
*What do you see instead?
test.js:4: SyntaxError: Unexpected identifier
throw err;
^
SyntaxError: Unexpected identifier
at test.js:2:3
If I just do eval('for i in range(10):'), I get the expected exception
message that shows where the syntax error is. Why does try & catch +
rethrow the error throws away that useful message?
