[Ardour-Users] Crash on Mac OS X

[Stephan Neuhaus]

Hi.

I am trying to move my Ardour recordings from an old version of Ardour  
on Linux (Intel) to the current version on Mac OS X (also Intel).   
Some sessions converted fine, but all lost their plugin settings (not  
surprising since I have only a few plugins installed).  Some sessions  
needed a bit of editing (mainly removing inserts), but this session is  
giving me real trouble, since it caused Ardour to crash.  I attached a  
gdb to the process and here is the backtrace.

If you need more info (such as the original and the edited session  
files), I can provide those, but I don't know if that's appropriate  
right now.

Ardour identifies itself as "ardour 2.8.2 (built from revision 5396)".  
Jack is "Jackdmp 1.9.2", "JackRouter 0.9.1", "JackPilot 1.6.5".  The  
machine is a MacBook running "2 GHz Intel Core 2 Duo", 4 GB 667 MHZ  
DDR2 SDRAM, fully patched (as of yesterday) Mac OS X 10.5.8.

Ah and one other thing: I gave a donation when I downloaded Ardour  
today.  Assuming that this is a problem with Ardour, and assuming it  
gets fixed and I need to download the fixed version, am I supposed to  
donate again?  (I'm not complaining, just asking.)

Best,

Stephan
