[maxmsp] pfft~, send~ and ASIO driver

Hi !

I am using an Edirol FA-101 (firewire) external audio card with MaxMSP on Windows (XP). Using the ASIO driver usually.
And I am experimenting at a moment several things around pfft~.

It appears that putting a send~ inside the pfft~ patch with this driver is crashing MaxMSP ! Sometimes with a message concerning the disallocation of the JVM (java)...

The weird thing is that it happens only with the ASIO driver of this only card and only with the send~ object.
If I change one of these parameter (like using the send object instead, or another driver), it's working normally !

I really have no clue about the why...

Maybe someone experienced this already ? Or have an idea of what's going on ?

Otherwise, this message can just be considered as a bug report.

Cheers
