Comment(by GeorgSWeber):
Guys, this problem is *by far* worse than I ever thought! I changed the
lines 1124ff in question in "modules/free_module.py" to:
{{{
sage: V = ZZ^7; V
Ambient free module of rank 7 over the principal ideal domain
Integer Ring
sage: W = V.base_extend(QQ)
sage: W._repr_()
'Vector space of dimension 7 over Rational Field'
sage: W
Vector space of dimension 7 over Rational Field
}}}
and this is the one failing doctest I get when running "sage -t -verbose
"devel/sage/sage/modules/free_module.py"":
{{{
Trying:
set_random_seed(0L)
Expecting nothing
ok
Trying:
change_warning_output(sys.stdout)
Expecting nothing
ok
Trying:
V = ZZ**Integer(7); V###line 1124:_sage_ >>> V = ZZ^7; V

ok

line 924, in __main__.example_23
Failed example:

Expected:
Vector space of dimension 7 over Rational Field
Got:
V
}}}
Unbelievable!
The problem seems to lie within the doctest framework ... does anybody has
experience with that? I think I stumbled once upon a time over temporary
files from doctests, does anyone remember where these are stored?
