Description
the code:
LIB"primdec.lib"; ring r=2,(v,u,z,y,x),dp; ideal i = z3+zyx+y3x2+y2x3, uyx+z2,uz+z+y2x+yx2, u2+u+zy+zx, v3+vux+vz2+vzyx+vzx+uz3+uz2y+z3+z2yx2; equidim(i);
results in:
Singular : signal 11 (v: 3106/2009082113): current line:>> ideal j=imap(gnir1,j);<< Segment fault/Bus error occurred at 2ba258577180 because of 10202 (r:1252081696)
The line that causes the error (ideal j=imap(gnir1,j);) is the inside equidimMax procedure.

seems to come from some undefined global vars in the conversion Singular <-> factory. Fixed in 3-1-0-6.
