Comment(by GeorgSWeber):
Some more tapping around in the dark:
{{{
EXAMPLES::
sage: testname = ZZ^7
sage: testname.base_extend(QQ)
Vector space of dimension 7 over Rational Field
}}}
gives:
{{{
**********************************************************************
File
"/Users/Shared/sage/test/sage-4.4.2/devel/sage/sage/modules/free_module.py",
line 1125:
sage: testname.base_extend(QQ)
Expected:
Vector space of dimension 7 over Rational Field
Got:
V
**********************************************************************
}}}
Amazing. Now try a bit "Eau de Cologne":
{{{
EXAMPLES::
sage: testname = ZZ^4711
sage: testname.base_extend(QQ)
Vector space of dimension 4711 over Rational Field
}}}
and this gives (repeatedly, several times):
{{{
sage -t "devel/sage/sage/modules/free_module.py"
[35.3 s]
----------------------------------------------------------------------
All tests passed!
Total time for all tests: 35.3 seconds
}}}
Hmm, I've got to stop here for today, but the next thing one might check,
is whether in (the doctest file of) free_module.py, somewhere there is
*another* "ZZ^7" lurking with the name of "V", getting loaded/dumped or
something like that ...
