[Mageia-dev] glibc-debug missing libc symbols ?

Apologies in advance if I'm just missing something obvious, but after 
installing glibc-debug, it seems that there are no debugging symbol 
files for common libc routines, e.g. vsnprintf(), even though their 
source is included in the package:

[root at ftgme2 ld.so.conf.d]# cd /usr/lib/debug/lib64
[root at ftgme2 lib64]# ls
libanl-2.14.1.so.debug           libnss_files-2.14.1.so.debug

libnss_dns-2.14.1.so.debug       libutil.so.1.debug@

[root at ftgme2 lib64]# grep cosh *
Binary file libm-2.14.1.so.debug matches
Binary file libm.so.6.debug matches
[root at ftgme2 lib64]# grep vsnprintf *
[root at ftgme2 lib64]#

I get hits on "fprintf", but not in any library I would think is 
associated with stdio-common.

Do we exclude these deliberately for some reason ?  Or am I totally off 
the mark ?
