[Ardour-Users] Ardour3 segfaults after build

[Edward Diehl]

I had successfully built and run several versions of Ardour3 on my  
AVLinux4.2 system, but now something has changed and now if I build  
Ardour3 it segfaults immediately:

$ ./gtk2_ardour/ardev

I can still run the Alpha4 binary from the Ardour website.  I've tried  
building several different versions of Ardour3 and they all get this  
error.  My biggest suspicion is that I upgraded my gcc version too far:
$ gcc --version
gcc (Debian 4.6.0-7) 4.6.1 20110507 (prerelease)

Any ideas about this problem?
Thanks.
