variable corruption bug

[Igor Schein <igor@txc.com>]

Hi,

? f()=polredabs(p=x)
? g(p)=for(k=p,p,f())
? g()
  ***   bug in gadd, please report

No mechanism in place to detect the improver variable use.  The above
is a result of a hard-to-spot problem with my scripts, due to the
missing local variable declaration, reduced to the bare minimum. 

Thanks

Igor
