Hello,

on OpenBSD (arch: sparc), I got a SIGBUS error during the compilation.

gdb info:
#0  0x089f136c in listextend (self=0xb6232d8, b=0xb611060) at /home/ports/pobj/Python-2.7.1/Python-2.7.1/Objects/listobject.c:838
838                 Py_INCREF(o);
(gdb) list
833             /* populate the end of self with b's items */
834             src = PySequence_Fast_ITEMS(b);
835             dest = self->ob_item + m;
836             for (i = 0; i < n; i++) {
837                 PyObject *o = src[i];
838                 Py_INCREF(o);
839                 dest[i] = o;
840             }
841             Py_DECREF(b);
842             Py_RETURN_NONE;
(gdb) print src
$1 = (PyObject **) 0xb61106c
(gdb) print i  
$2 = 1
(gdb) print *src
$3 = (PyObject *) 0x8d8afdc
(gdb) print src[i]
$4 = (PyObject *) 0x0

Attached file is the complete log file.

Thanks,

Remi.

This bug seems to be the same than 7424:
http://bugs.python.org/issue7424
Sorry I didn't seen it before.

For your information, this bug has been fixed in OpenBSD and the developper has contacted the NetBSD developper:
http://marc.info/?l=openbsd-tech&m=140209064821540&w=2

So I think we could close this issue because it's a system issue, not Python.
