[New-bugs-announce] [issue10186] Invalid SyntaxError pointer offset

[Alex]

New submission from Alex <malicious.wizard at gmail.com>:

Builtin SyntaxError formatter does never point to char before last in wrong source line. traceback.format_exception() is not affected.

*** Example:
>>> raise SyntaxError('', ('', 0, 3, 'hello'))
...
    hello
      ^
SyntaxError: test
>>> raise SyntaxError('', ('', 0, 4, 'hello'))
...
    hello
       ^
SyntaxError: test
>>> raise SyntaxError('', ('', 0, 5, 'hello'))
...
    hello   # <-- note that it's not "o"
       ^
SyntaxError: test
>>> raise SyntaxError('', ('', 0, 6, 'hello'))
...
    hello
         ^
SyntaxError: test
