Problems with libc6 symbols

[Eran R. <ER...@il...>]

Hi All,
Am new to OProfile, so apologies if this issue was brought and resolved
before.
(my searches so far did not help though).
As the subject mentions I fail to see any debug symbols from libc.

root@box1:/# opreport -l
samples  %        samples  %        samples  %        image name
app name                 symbol name
1890     16.0714  3684     28.9691  3192     29.3977  libc-2.9.so
libc-2.9.so              /lib/libc-2.9.so

The debug symbols are there and match though:
root@box1:/# opreport -V bfd -l
...
looking for debugging file libc-2.9.so with crc32 = dcd904d7
found /usr/lib/debug/lib/libc-2.9.so with crc32 = dcd904d7
now loading: /usr/lib/debug/lib/libc-2.9.so
bfd_info::get_symbols() for /usr/lib/debug/lib/libc-2.9.so
bfd_get_symtab_upper_bound: 58656
bfd_canonicalize_symtab: 7331
...

Done some printing within libutil++/op_bfd.cpp op_bfd::get_symbols I
learned that:
1. The number of symbols in ibfd are zero (perhaps this is expected)
2. The number of symbols in dbfd are 7331, HOWEVER, all of them get dropped
on being uninteresting (e.g. __vprintf is dropped on SEC_LOAD flag)
Seems like there is a compatibility problem between libc and binutils. Even
if this is the case I am not sure what to do.
Let me know if I should post this somewhere else.

Thanks very much,
Eran
