Hi!
The following happens on Intel(R) Core(TM)2 CPU, openSUSE 11.0
(X86-64), sage 4.1.
It does not happen on sage.math.
Consider the following code in listtext.pyx:
def ListTest(int n):
cdef dict D = dict(zip(range(1,n+1),range(n)))
cdef list L = n*[0]
cdef int i
for i from 0<i<=n:
print len(L), D[i]
print L[D[i]]
L[D[i]] = D[i]
Now, start sage and do
sage: attach listtest.pyx
Compiling /home/king/SPKG/tests/listtest.pyx...
sage: ListTest(10)
10 0
0
ERROR: An unexpected error occurred while tokenizing input
The following traceback may be corrupted or invalid
The error message is: ('EOF in multi-line statement', (355, 0))

12 print L[D[i]]
---> 13 L[D[i]] = D[i]

IndexError: list assignment index out of range
Why is the index 0 out of range, for a list of length 10? Why can I
read from L[D[i]], but not assign to it? And why is the error
different (without the "EOF in multi line statement" bit) if the line
print L[D[i]]
is removed? Is somebody able to reproduce the problem?
Best regards,
Simon
