Description

Sometimes the CoCoA-5 test SourceAnna fails (on 64-bit MacOSX).

The problem appears when executing the line:

TEST_ASSERT(HilbertPoly(Qxyz/ideal(x,y^2)),  2);

History

#1 Updated by John Abbott over 9 years ago

I have already reported by phone that there is a problem (with SourceAnna) on 32-bit Linux.

On my 64-bit MacOSX the test sometimes passes and sometimes does not. I tried running just the specific line several times in a fresh CoCoA-5, and no problems arose.

Running some of tests line-by-line, the following happened (after several repetitions):

>>> TEST_ASSERT(HilbertPoly(Qxyz/ideal(x,y^2)),  2);

***************************************************************************
****CoCoA ERROR****  ErrCode: CoCoA::ERR::IdealNotInRing
****CoCoA ERROR****  Message: Incompatible ring and ideal: ideal is not in the given ring
****CoCoA ERROR****  Context: NewQuotientRing
****CoCoA ERROR****  File:    QuotientRing.C

--> ERROR: Incompatible ring and ideal: ideal is not in the given ring

I cannot reproduce this error. Postponing to next version.

I have not noticed any problem like this lately; perhaps it has resolved itself magically?

Mark as "closed"?
