If you mean the failure in singular/polynomial.pyx, it looks more like a
memory leak:
sage -t --long src/sage/libs/singular/polynomial.pyx
**********************************************************************
File "src/sage/libs/singular/polynomial.pyx", line 166, in
sage.libs.singular.polynomial.singular_polynomial_call
Failed example:
leak(10000)
Expected:
0
Got:
83886080
**********************************************************************
1 item had failures:
1 of 12 in sage.libs.singular.polynomial.singular_polynomial_call
If I replace the lines
sage: leak(10000)
0
with 10 such doctests and run "sage -t" repeatedly on the file, I get
between 1 and 4 failures each time.
