I wonder if there is a limitation on the number of arguments to an ftgen call ?

One of my students got into trouble when trying to render the attached
file (simplest.csd),
but if I just delete some lines of the ftable data, it runs fine
(simplest1.csd).
I wonder if there is a limit of 100 arguments or so ?

Oeyvind

Oeyvind,

Both of your attached CSDs worked for me with Csound 5.10.  There is a limit
to the number of opcode arguments, but from looking at the code I think it
is around 1000.  I did notice that one of your files had just over 256
arguments, and another had just under that (256 being a popular number for
programmers ...)  *shrug*

Are you still having this problem?  Which version of Csound was your student
using?

The student was using 5.09 on OSX,
but also tried 5.10 and 5.07.

I tried it with 5.10,
and also with my compiled version here (not updated from CVS for a while).

He said to me toady that "it sometimes work, sometimes not", which is
even more puzzling.
Maybe it has to do with GEN08 then ?

I suggested he use gen02 or gen23 to input the values, and then use
gen30 to "interpolate" the data,
this worked for him.
Still the issue with gen08 seems strange.

What does Csound do when it misbehaves?  Print out an error message?
Segfault? Just produce incorrect results?

What platform is this on?  I was testing on Mac OS X.  Perhaps there is an
issue with line endings or \ on one of the other platforms.

On windows it segfaults,
I don't recall the exact error message on OSX, but it exits
immediately, like a segfault at the table load time.
I don't think it's to do with line endings (line continuation),
because the original script did not use these. We tried with the line
continuation to be able to better count the number of arguments
allowed before crashing.

OK, there is definitely a problem here but it doesn't always show up after a
certain number of arguments or line length.  I experimented with adding more
arguments to the ftgen statement and with just two to eight more it
segfaults but with ten more I get strange behavior where kr or ksmps is
overwritten with the value for 0dbfs.  Very strangely, this also happens if
I comment out the extra lines!

I tried running GDB, but I really do not know how to use it yet.  So I am
going to have to hand this one off to someone else.  Here is the end of the
output from GDB that I got when I ran the attached CSD:

strsav_string is in namedins.c

Edit the function. Add several printf. Display the content
of s, n, h, ssp and so on.

"s = %s\n"
"h = %d\n"
...

Add a printf before each comment...

// here
/* now find entry in database */

//here
/* not found, so need to allocate a new entry */

...

so that you can see where it stops.

Yes, I can confirm that the overwriting of kr or ksmps happened on the
student computer as well.
I was not able to reproduce that same (kr) error on winXP.
