Dear list,
I have been experiencing mysterious bugs and crashes when using the [text] object. Most of the time it's working fine and I really enjoy the functionality. But sometimes the output of a certain operation is just wrong. And there have been several occasions where Pd would crash and close silently! Only once I got an error message in the Pd console and it said something about 'binbufs'.
The bad thing is: I can't reproduce any of these errors. Right now I'm using Pd 0.46-6 on Windows 7.
My first question: Have you experienced silent crashes of Pd when using the [text] object?
My second question: Could you quickly try out the attached patch and tell me what happens for you? You only have to press 6 bangs and watch the Pd console.
as with most "myterious bugs", this seems to be related to memory corruption. (which explains everything from crashes to crop circles).
while i do get "symbol foo" when pressing (4) under "normal circumstances", i get "1" when running under valgrind. more interestingly valgrind bitterly complains when i first write "symbol foo" into the [text] (3):
