Another topic to be documented.

I know, you are right, that's only a workaround, but the occurrence in memory manager leaves there variables that after some time could interfere with other commands or programs...
We need a real solution :-)

I added to the posted program the two lines with purge(u) and purge(v) and made u and v local until the problem is solved.

you have done well. When there will be a better solution we'll be able to avoid local u and v and also purge()...

I have done the same in my program for Linear and curvilinear integrals (in Library) for the same purpose.

There is no better solution! Declaring symbolic variables as local variables and purge them after (or assume(.,DOM_SYMBOLIC)) is the recommanded way to use symbolic variables in a CAS function.

well, thank you. I'm using this method and it's ok.
