- I hope this is not one of those well known bugs. If so please
- send me a pointer to a FEB (Frequantly Encountered Bug) list!
-
- Playing with MapleV I found out that sometimes it crashes
- pretty badly trying a simple limit, it simply runs out of
- memory!
-
- > limit(ln(abs(x))*x,x=0) ;
- bytes used=1000436, alloc=786288, time=9.883

- If we try with the right condition: sometimes it works some it doesn't.
-
- > limit(ln(abs(x))*x,x=0,right) ;

- From the left it also crashes...

- Does anyone know why this crashes Maple. Also, Mathematica won't
- do it, but it does not crash..
