I agree with what you say.
that may justify the interpreter to crash.
(with all the other pages I had opened in the other tabs), that IS a bug of
*Its execution* may even become unstable (and that of all simultaneously
running patches, since the PD "virtual machine" is not and is not supposed
nor expected to be a "multitasking" virtual machine where patches are
independent programs) but I still MUST be able to save the patch, and close
one or all the patch windows.
If I can't do that, then PD has a bug. I am not saying that the developers
of pd should be scorned for that, nor that it easy to fix, nor even that it
is worth wasting time fixing it, but it is a bug.
The interpreter or virtual machine of an interpreted language is a software,
and the interpreted code is its input. The "virtual" machine can became
"virtually" unstable if it is running buggy code. But the "real" software
that simulates the virtual machine must keep stable; if it triggers
(legitimate) operating system's defense mechanisms, the interpreter is buggy
The case of C is different, because it is a compiled language that produces
real machine code which will run (and crash) directly on the real machine.
It is the programmer's responsibility to avoid writing code that will
crash - though it is the operating system's responsibility to avoid that its
crash affects other programs running simultaneously.
Obviously this has no relevance to the original discussion about the
namecanvas but I thought it was interesting as a general matter. And I
preserved the subject to keep it identifiable as a followup to that thread.
