Here's a shorter version:

import codecs decmap = u"".join(unichr(i) for i in xrange(256)) print type(codecs.charmap_build(decmap))

The source fo the crash is the EncodingMap type (defined in unicodeobject.c); it has an invalid type:

Breakpoint 2, PyUnicode_BuildEncodingMap (string=0x2b97d44dbf40) at Objects/unicodeobject.c:3213 (gdb) print EncodingMapType $1 = {_ob_next = 0x0, _ob_prev = 0x0, ob_refcnt = 1, ob_type = 0x0, ob_size = 0, tp_name = 0x53d15a "EncodingMap", tp_basicsize = 80, [...]

Did someone forget a PyType_Ready() call when EncodingMap was added? (And what other types are missing PyType_Ready() calls? :)
