Trying to debug in issue in my code

Hi, I am trying to debug an issue in my code, and want to gain a bit more visibility on the issue.

My crash is:

Thread 1 "connectwave" received signal SIGSEGV, Segmentation fault.

I gather that the target routine of the crash, alsa_lib_resampler_process_int(), is in the alsa-plugins module, so I downloaded alsa-plugins-1.2.5
just so I could gain some insight into what the code is doing when it crashes. I should state quickly here that I believe the crash is my fault,
but I am just trying to figure out why it is happening.

I was unable to find the routine alsa_lib_resampler_process_int() in that package. Also a ./configure followed by make does not
work on it (goes to the idea of substituting my own compiled .so for debug purposes):

/home/samiam/projects/alsa/alsa-plugins-1.2.5/usb_stream/pcm_usb_stream.c:480: undefined reference to `snd_config_get_card'

Although obviously I didn't put a lot of effort into making it work.

DId the routine alsa_lib_resampler_process_int() get eliminated in later editions of the plugins? or am I looking in the wrong
place?

Thanks in advance,
