#5548: fix that _hnf_mod segfaults sage completely
----------------------------+-----------------------------------------------
Reporter: was | Owner: was
Type: defect | Status: new
Priority: major | Milestone: sage-3.4.1
Component: linear algebra | Keywords:
----------------------------+-----------------------------------------------
{{{
teragon:algebras wstein$ sage
----------------------------------------------------------------------
| Sage Version 3.4, Release Date: 2009-03-11 |
| Type notebook() for the GUI, and license() for information. |
----------------------------------------------------------------------
sage: a = random_matrix(ZZ,16,4)
sage: a._hnf_mod(100)
------------------------------------------------------------
Unhandled SIGFPE: An unhandled floating point exception occured in SAGE.
This probably occured because a *compiled* component
of SAGE has a bug in it (typically accessing invalid memory)
or is not properly wrapped with _sig_on, _sig_off.
You might want to run SAGE under gdb with 'sage -gdb' to debug this.
SAGE will now terminate (sorry).
