Hello (and thanks for chuck!),

I'm having problems with chuck and libsndfile on linux (FC4,
2.6.14-0.10.rrt.rhfc4.ccrma, libsndfile version 1.0.11-1.rhfc4.ccrma). 
It crashes 90% of the time when trying to the load the example data
files in the "otk_0x.ck" series with the following message: User defined
signal 2.

In src/util_sndfile.h, it looks like it's expecting version 1.0.10. So,
that could certainly be the problem:

#define PACKAGE "libsndfile"
#define PACKAGE_BUGREPORT "erikd at mega-nerd.com"
#define PACKAGE_NAME "libsndfile"
#define PACKAGE_STRING "libsndfile 1.0.10"
#define PACKAGE_TARNAME "libsndfile"
#define PACKAGE_VERSION "1.0.10"

I haven't tried installing 1.0.10 yet (its not in my distribution), but
I tried upgrading to the latest FC4 version ( with no luck. 


BTW-- Here's the stack trace in debug-mode:
