RandConstrainedMNormal crashes Tol Base

Reported by: mafernandez Owned by: Jorge

Description

The Matrix function RandConstrainedMNormal causes a crash in Tol base when some of the optional arguments are not given. Consider the following example below:

Matrix mu = Col(2.0, 2.0);
Matrix COV = ((1.0, 4/5.0),(4/5.0, 1.0));
Matrix B = ((-1.0, 1.0), (0.0, -1.0));
Matrix b = Col(0.0, 0.0);
Matrix sample = RandConstrainedMNormal(mu, COV, B, b, 1, 100);

Hi Miguel Angel,

I've tried the sample code you provide (that is the same provided by the function) and I get a suitable behavior. Removing the two last optional parameters seems to be good as well.

BTW, I'll ckeck this with you tomorrow.

Thanks for your report.
Daniel

when x0 is not given a null pointer dereference take place.

That bug was introduced between releases r1.7.2.2 and r1.7.2.3 at branch 1.1.5 and between releases r1.8 and r1.9 at branch trunk (1.1.6)
