i know, i know, but it shouldnt crash the program?

great!

the difference is:
the second works, the first doesn't.

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(a)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 (1.0.11.3) with no luck.
