R devel - Feb 2000 - Problem with expression evaluation depth (PR#436)

Hi,
I'm having problems with the check of
infinite recursion in the expression evaluation 
depth.
The problem appears in a program with no recursions
whatsoever. The layout of my program is a series
of routines called by a big loop.
I printed out depthsave in  src/main/eval.c
and it appears as there is an error popping out
the length of the expression stack, R_EvalDepth,
somewhere. As the loop goes, R_EvalDepth goes up
and down, but in average, it alway increases.

For the moments, I commented out the check with
options$expression and my program finished succesfully.
Any help would be appreciated.

Sounds nasty, but I think we need to have a code sample exhibiting the
behaviour in order to investigate it. Could you try shaving your
example down to something smaller which still has the problem?
