[alsa-devel] A debug version of the ALSA lib?

I have a problem with the ALSA library. Calling snd_device_name_hint() crashes
sometimes, and I can't understand why.
It might be due to a previous memory corruption in my program, a problem with
my sound card driver, or a bug in the library, I don't know.
I tried to debug it in assembler, and found that the library is browsing a list
of devices, gets the pointer to each device name, and in the 2nd device, I get
the four letters "Play" instead of a valid pointer.
To be able to go further, I'd need a debug version of the ALSA library,
including variable names and source lines, which could let me find more easily
what goes wrong and when.
Is it possible to build such a library from the alsa-lib-22.214.171.124 sources?
Or should I download and install another specific package?
