#355 closed bug (fixed)

A simple way to crash singular

Reported by: gorzel Owned by: somebody
Priority: minor Milestone: 3-1-4 and higher

Description

The following typo in the ring definition makes Singular crash:

> ring 0=0,x,dp;
Singular : signal 11 (v: 3132/ 14363 ):
current line:>>ring 0=0,x,dp;<<
Segment fault/Bus error occurred at 80ac5f8 because of 0 (r:1313067660)
please inform the authors
trying to restart...

Although error-messages exists for these cases:

> ring 0;
> basering;
   ? `basering` is undefined
   ? error occurred in or before STDIN line 2: `basering;`
> 0=0,x,dp;
   ? assign not impl.
   ? error occurred in or before STDIN line 3: `0=0,x,dp;`

Above, I would expect an error message as with this typoe here:

> ring r=0,x,qp;
   ? wrong ring order `qp`
   ? cannot make ring
   ? error occurred in or before STDIN line 6: `ring r=0,x,qp;`
   ? expected ring-expression. type 'help ring;'
