[PD] Strange PD crash with ASIO ...

[oliver]

Hi, dear list !

Just stumbled across a (probably serious) issue with new PD 0.52

Here's the scenario, on Windows 7 / PD 0.52.1 /64bit:


1.) ASIO with multichannel soundcard (ESI GIGAPort HD)
2.) blocksize 512 / delay 6 (clear sound with "test audio & midi")
3.) a patch (with dsp on) that uses either [env~] or [avg~] or 
[sigmund~] or any signal to float/list conversion process
4.) those floats are converted back again to signals
5.) cutting/deleting any of the "signal->float" connections or 
numberboxes crashes PD


I attached a simple (rather dumb) patch to demonstrate the principle

The crash reliably happens when i disconnect any number box attached to 
[env~]. also changing [env~]'s window size doesn't help

This crash doesn't happen when i use PD 0.51 instead !


As i wrote in the subject, this crash happens ONLY with ASIO as the 
audio driver (also true for "ASIO4ALL"), but not with the MMIO driver.

could you dear windows PD users please test the attached patch and 
verify/falsify my observation ?

best

oliver
