Thanks for the advice Dan... I've not found anything memory management wise but think I've found the issue.

I've just tested my ugen about 30 times and it now seems to be running without issue. Of course with these sort of problems it can be difficult to tell if its fixed or not!

Is it possible that initialising m_fbufnum to -1e9f could have fixed the issue?

Is it possible all of this was down to the buffer not being ready for reading something?

Many thanks,

Tris

Hi Tristan,

Well, I had a look, but I'm afraid I saw no glaring errors.
Inconsistent crashing often indicates bad memory accesses, and in SC
plugins these can be tricky to detect using developer tools. I guess
at the least, I'd suggest temporarily adding some checks that your
indices into the buffer data are sane.

Best
Dan
