Sampling color at vertexes

Doing some simple detective work I found out that what is causing the crash in SampleColorAtVertices is the line:

Sampler smpl;

If I place a return INIT_SAMPLER_RESULT_OK; before this line, no crash occurs.
If I place a return INIT_SAMPLER_RESULT_OK; after this line, the crash occurs.

Hi
This seems to be a problem in the constructor.
Sampler::Sampler() { ... }

But it is imposible to say exactly what causes this crash without knowing what was changed in the code.

Have you changes something in this code section ?

  
	AutoAlloc<VolumeData> vd; //Owning ptr 	  
AutoAlloc<TexData>	 tex; //Owning ptr  

Because this will auto alloc vd and tex.

This is what I have:

Well then it will be cause by some changes in the constructor.
Sampler::Sampler()

Well, the listing is a bit long. Should I paste it here or should I send it over through e-mail? (if I can, of course... I don't want to be imposing).

Of course you can send it over e-mail.
Even better just place it on github.com

Mustn't I have an account in github.com to place something there?
And, if I send you the listing over e-mail, can I use the mail I used when I bought some of your plugins? 🙂

Since you're having so many problems with this. I decided to create a DescriptionToolData plugin myself.
I used your Message() code for the getting the object in the linkbox gizmo.
And I used the same Sample class code I sent you in my CD plugin.
I also used a separate .h file to host that code. Using #include "sampler.h" to point to the code from the plugin's .cpp file

It all works fine for me and does not crash at all. I can't undestand why you're having so many problems with it.
Would you like me to send you my tool plugin?

I think yes.

Or just PM me here, whatever you want 🙂
Note: I do not ready my e-mails often. Some times for many days.

Thank you to both.
I will try take a look at Scott plugin and compare it with mine first.
I hope I find my mistake (I'm assuming I must be doing something wrong).
If I still don't manage to fix it, I will send you my code through PM, Remo.
Ok?

So, if you don't mind, Scott, I would gladly take a look at your plugin.
Same batchannel, same bat-mail 😉

I'm still cleaning up (it still hanged my code 😞 )
In the meanwhile, let me tell you guys one thing that may help pinpoit the problem.
Xcode is giving me a warning in the line:

GeDynamicArray<Colors> colors(pcnt);

The warning is: Template argument uses local type 'Colors'

What is this?!?

Remo, I have sent you an mail (and a movie through wetransfer) to your gmail account.
I don't know if it is still active, though.
