Comment:
Hmm. I think this might have something to do with one of the things I saw
on #9247.
I'm attaching the reviewer patch, which causes the following:
{{{
sage -t "devel/sage-
main/sage/schemes/elliptic_curves/ell_modular_symbols.py"
**********************************************************************
File "/Users/rlmill/sage-4.5.eclib-test/devel/sage-
main/sage/schemes/elliptic_curves/ell_modular_symbols.py", line 429:
sage:
M=sage.schemes.elliptic_curves.ell_modular_symbols.ModularSymbolECLIB(E,-1)
Expected nothing
Got:
Warning : Could not normalize the modular symbols, maybe all further
results will be multiplied by -1, 2 or -2.
