"Program terminating" with oldFactArg and dot products

[t-hahn]

I'm getting program aborts ("Program terminating in line ...") if I use factarg with oldFactArg on expressions containing dot products. See here:
v e1, e2, k1, k2;
s a, b;
cf dotM;
L testbad = dotM(e1.k1*e2.k1);
L testok = dotM(a*b);
.sort
on oldFactArg;
factarg dotM;
print;
.end

Best, Thomas

Forgot to mention: this happens with form/tform compiled from yesterday's sources.
I checked with the version of April 19 that I was using before and there it doesn't happen.

Here is another example of the crash of OldFactArg:

On OldFactArg;
V p1,p2,p3,p4;
S x;
CF f;
T t;
L OK1 = f(t(p1)*x);
L OK2 = f(t(p1,p2)*x);
L OK3 = f(t(p1,p2,p3)*x);
L BAD = f(t(p1,p2,p3,p4)*x);
factarg f;
P;
.end
