Is there currently a limit on the nesting level of includes?

I'm trying to make the ImproSculpt4 code run again, it worked on 5.13,
but I have a hard time debugging why it does not run now (tested on
5.19 and on 6). In Csound 6 I get a
Cannot open #include'd file
.. and here usually the file name of the not-included file is printed,
but I get only a blank line.
I've chased it down to the actual place in the code that triggers the
error message, but there is nothing out of the ordinary happening
there. If I paste the code of the included file into the file from
which it was included, then the error goes away. Not sure how many
levels of include nesting I have here, but roughly between 5 and 10.

I beloieve the limit is just memory

Hm, then what could it be that makes it fail for me?,
it is probably unlikely that the memory imposes any practical limit
here (?) Since I'm only using includes "a few" levels deep

There used to be a limit of 100 fir nesting of includes and macros, but 
that got largely removed in the rebuild of the new parser.

Just noticed it has crept back -- linit of 100 anf should give error 
message of "Includes nested too deeply" or "macro_stack_ptr beyond end"

Sorry I thought I had unwound that limitation.  Will think about it.  It 
is "easy" to increase this to any finite limit but it would be better as a 
flexible vaue

Thinking out loud... could realloc the array and delete at end.... humm on 
release day too.

I have written the code but so far not found a reasonable test.  It should 
expand the stack to arbitrary size.  Works if not used!  The example in 
the manual is for a score include which will be harder.

Anyway should be working today (weather permitting)

In the develop tree, for orchestra includes/macros only.
Limit is now 1024, imposed by the error reporting mechanism for 
vbacktracing.  This could be removed if one is willing to have reduced 
error reporting

That is excellent, should be enough :-)

My code however, was only 4 includes deep, and it is stubborn, I
managed to make it run if I copy the code from the deepest include
into the next-to-deepest one.

The new csound code debugger will be very very useful in such cases,
Andres, will it be able to work with code split into several files
(includes) and macros?

If Csound allowed 100 levels and your code was breaking down at 4, then this smacks of a bug.

Agreed,
but it is hard to figure out the cause and to contruct a minimal example,
since the offending code is not offending if it is moved somewhere
else (i.e. not in an included file).

speaking of such debugging,
where is the parsed output kept (is it kept?), can I run just orhestra
parsing and then write the output to a single file?
That way I could compare the two versions of the code (with or without include).
