Will do.

AFAICT that's a regression due to the way Pd Vanilla implemented message forwarding for

[inlet~ fwd]. That's a feature that allows a signal inlet of a subpatch/abstraction to forward

non-signal messages to the right outlet of [inlet~ fwd]. (The right outlet sprouts when the

"fwd" argument is present.)

Another regression-- there is no longer an error if you try to send a non-signal message to

[inlet~].

Another regression-- [inlet~ fwd] unconditionally allocates space on the stack to copy the

entire incoming message. If you generate a long enough message this will blow the stack

and cause Pd to crash. Esp. important given that Windows stack is much smaller than the RAM

available for heap allocation on most machines.

Also-- I *think* Pd Vanilla doesn't forward pointer messages through [inlet~ fwd]. It appeared to be an oversight-- at least I didn't see any comment about it.

A GSoC student spent some time reimplementing this in Purr Data, so none of thiese should be

issues there.

Before you ask that, have a look at the PRs. You can view the list of open PRs for Pure Data Vanilla here:

https://github.com/pure-data/pure-data/pulls

It appears Christof (Spacechild1) submitted a patch for this almost a month ago. So it wouldn't make sense to send another

PR for this same fix. Christof's patch should work just fine to solve these issues.

If you're asking in general, that's unfortunately just not practical. We'd have to manually create a new patch set and test it

for Vanilla, for (nearly) every single change we make. It's much easier to just report here when I find crashers-- Miller and Christof

are quite quick to fix them. They know the Vanilla build/test/development process much better than I do so that seems the much preferable route for everyone involved.

Best,

Jonathan
