In my quest to build an AU version of Cabbage I've hit an issue with
the Csound library. The reason I assume it's something to do with
Csound is due to the fact that not calling Csound gets rid of the
error. Here's is what the console says:

10/11/12 5:07:52 PM	[0x0-0x19c99c8].org.ardour.Ardour2[38032]	JUCE v2.0.25
10/11/12 5:07:52 PM	[0x0-0x19c99c8].org.ardour.Ardour2[38032]	File
exists:/Users/walshr/Library/Audio/Plug-Ins/Components/CabbagePluginOSX.component/Contents/CabbagePluginOSX.csd
10/11/12 5:07:52
PM	[0x0-0x19c99c8].org.ardour.Ardour2[38032]	Ardour2.bin(38032,0xa049d540)
malloc: *** error for object 0x17dedc20: pointer being freed was not
allocated

The other thing that leads me to believe this is an issue with the
Csound lib is that I use smart pointers only, and from my
understanding of the above problem, it's highly unlikely to occur when
using smart pointers. The other odd thing is that it only appears when
I try to launch a Cabbage AU in Ardour. There is no crash with other
hosts. Perhaps it's not an issue with Csound at all, but I'm certainly
stumped. And I'm a total OSX noobie! Any help in debugging would be
much appreciated!

Can you run this on gdb and see where the crash is?
You can attach GDB to ardour's PID and see if you get backtrace

$ps -u

to get the PID

then use the attach command in gdb

I am not a noobie on OSX -- mre of a neveroo
But,  does valgrind run on OSX?  That would identify a false free.
Otoh I have never heard of smart pointers either

Just trying that now. The problem is that as soon as I attach Ardour's
process to gdb it renders Ardour useless. I get that little beachball.
It just keeps spinning and spinning...does it spin anti-clockwise in
the southern hemisphere? Ok, now to Valgrind, but I'll have to built
it myself first I think.

I'll take a look at Valgrind. Smart pointers are a C++ thing, auto
garbage collection thingymabobs. Great for people like me who tend to
play loose and fast with memory!

Are you pressing c to continue once you attach?

Thanks Steven! Nice idea! Ok, once I try to open a Cabbage plugin I
get the following before it hangs:

Reading symbols for shared libraries ........... done
Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: KERN_PROTECTION_FAILURE at address: 0x00000184
0x17df01a3 in opcode_list_new_oentry ()

Arhh   all that effort trying to educate students to Do It Right being
nullified by yeaky code.......

This is what the backtrace says:

(gdb) c
Continuing.
Reading symbols for shared libraries ............ done

Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: KERN_PROTECTION_FAILURE at address: 0x00000184
0x17df01a3 in opcode_list_new_oentry ()

The sequence of call to the Csound API is as follows:

csound = new Csound();
csound->PreCompile();
csound->SetHostData(this);

The takes place during the call to PreCompile(). If I take out the
call to PreCompile I get a different set of errors, but I fear that
might not be the best tack to take. Also, I have to point out that
this happens only with Ardour. My Csound driven plugins works in other
AU hosts. Any suggestions?

Could you give us the other set of errors mentioned?

Also, what is the exact message that the bt command prints?

The exact message is:

(gdb) c
Continuing.
Reading symbols for shared libraries ............ done

Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: KERN_PROTECTION_FAILURE at address: 0x00000184
0x17df01a3 in opcode_list_new_oentry ()
(gdb) bt
#0  0x17df01a3 in opcode_list_new_oentry ()
#1  0x17df0274 in csoundAppendOpcodes ()
(gdb)


If I take out the call to PreCompile(), so my sequence of calls now
looks like this:

csound = new Csound();
//csound->PreCompile();
csound->SetHostData(this);

csound->SetExternalMidiInOpenCallback(OpenMidiInputDevice);
csound->SetExternalMidiReadCallback(ReadMidiData);
csound->SetExternalMidiOutOpenCallback(OpenMidiOutputDevice);
csound->SetExternalMidiWriteCallback(WriteMidiData);	

csCompileResult = csound->Compile(
const_cast(csdFile.getFullPathName().toUTF8().getAddress()));

I get errors relating to the MIDI callbacks.

(gdb) c
Continuing.
Reading symbols for shared libraries ............ done

(gdb)

I think these errors are a results of not calling PreCompile(). If I
take out the MIDI callback stuff, and PreCompile() I get the same
errors as before on the Compile() call.

OK, thanks, so we know it's a problem when loading opcodes. I'll look at it now.

One thing you could try, just to narrow down the search for us, is to hide the opcode directory, the one in the framework,
then run again. This will allow us to see if the issue is with one of the plugin opcodes.

You could hide it by either renaming it or by setting the OPCODEDIR etc variables in .MacOSX/environment.plist

Steven suggested I try that too, but in the end it didn't make any
difference. Same errors as before.

Ok, so it's earlier than that. I am looking at a possible bug now, and I'll let you know.
