Current master on csound5 is segfaulting, null pointer reference in
argtyp2. Csound6 is working, though.

What is the status on csound5? Are we supposed to push fixes to csound5 too?

This is likely the same bug I saw with the fix John put in for the arg
checking. I had to revert to get a working csound5 here, but I haven't
had a chance to investigate.

can you supply an example of it failing?  So far it appears to work for
me, but mainly I am using cs6.

Sorry but I have atually no memor of what (a) i changed or (b) why,

Hi John,

The change was this commit:

http://csound.git.sourceforge.net/git/gitweb.cgi?p=csound/csound5.git;a=commitdiff;h=eca7db266d0df5d9d14a449ac3bbe5dd4c1301ca

I think it has to do with calling set_xincod being moved to before the
outargs code.

I don't have a simplified example here, perhaps Felipe has one he can send.

Nope, I'm testing with trapped.csd or xanadu.csd.

However, it seems a large portion of the tests are failing with error:
error: inconsistent sr, kr, ksmps:

I was attempting to help Menno yesterday and he was getting kr set to 1
when it should be 1500.  I cannot reproduce here.  He was using ubuntu I
think with gcc 4.6.3, while I have openSuSE and gcc 4.5.1

I have looked at that code and it has ot changed for ages.  I am
suspecting miscomplation at present as that seems only option.  code is in
Engine/csound_orc_compile.c

I will look again but being unable to repeat it is unlikely that i will
find anything.

regarding the segfault I get it in trapped but not in my simple examples. 
Happens in the complex code to determine types with a null pointer  No
idea (yet) what is happening or supposed to happen

The old code is certainly wrong.  It marks variables on LHS before
checking the RHS for defined.  I would much rather work out what is wrong
with the null pointer.

Also there is the inconsistency on Xubuntu not found on OpenSuse.  May be
in Debin as well

This is due to the code for resolving sr/kr/ksmps being don twice, once in
new parser and then again in old parser.  I think I have a fix --

I can confirm getting the same thing as Dr. B. I did a quick test with
CsoundQT (float version) with the Pipe Demo and virtual keyboard.
What I see is the keyboard comes up, I hit the keyboard keys and see
rtevents in the console, then when I go to CsoundQT's interface to
modify a slider it hangs.

I think the ideal solution would be as Dr. B suggests, which is to
have a virtual keyboard native to CsoundQT (perhaps in a panel).  The
code for the FLTK one is in C++ if I remember correctly; if so, it
could make it a good candidate to use as the basis for a QT version.
(I think Rory has based his VK in Cabbage on that code, and I based my
blue virtual keyboard on it as well, and the iOS example virtual
keyboard mostly on it too).  I don't know if anyone has any time to
implement anything like this though in the short term; perhaps a
feature request item that'd be nice to have.

I don't know what's changed in Csound though to cause a bug like this,
as the version of CsoundQT I'm using hasn't changed in a long time.
On the other hand, I don't have any prior comparison with earlier
csound versions as I don't use the virtual keyboard with CsoundQT all
that much.

Hopefully someone else can lend a hand with diagnosing this!

Two comments:

1:  cannot the second loop happen with the first?  Just wondering

2:  commit it as it seems OK and better than current state

Hi,

Yes, I've seen this problem too. I was talking to Iain yesterday about
it, and I will add a virtual keyboard widget. It's a good idea to
start from the FLTK virtual keyboard, it might save some time.

Cheers,
Andrés

No, you can’t use any FLTK widgets with CsoundQT. The two graphic systems are not compatible.
To use the virtual keyboard, you need to run Csound on the terminal (you can use run in term from
CsoundQT if you wish). There is no solution for this problem and it is not a Csound bug.
