[issue7330] PyUnicode_FromFormat segfault when using widths.
|
|
New submission from Mark Dickinson <dickinsm [at] gmail>:
There seems to be something wrong with the width handling code in
PyUnicode_FromFormat; or perhaps I'm misusing it.
To reproduce: replace the line
return PyUnicode_FromFormat("range(%R, %R)", r->start, r->stop);
in range_repr in Objects/rangeobject.c with
return PyUnicode_FromFormat("range(%20R, %20R)", r->start, r->stop);
On my machine (OS X 10.6), this results in a segfault when invoking
range_repr:
Python 3.2a0 (py3k:76311M, Nov 15 2009, 19:16:40)
[GCC 4.2.1 (Apple Inc. build 5646)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> range(0, 10)
Segmentation fault
Perhaps these modifiers aren't supposed to be used with a width?
