Unit error using sqrt



Hello,

 

I am using XMaxima 5.10 for Windows.

When I enter the following commands

load("unit")$

sqrt(2*m^2/s^2) I receive the following error

 

Maxima encountered a Lisp error:

 

 Error in MACSYMA-TOP-LEVEL [or a callee]: Bind stack overflow.

 

Automatically continuing.

To reenable the Lisp debugger set *debugger-hook* to nil.

 

Thank you for your help.
