This repros with the nm from the AIX toolbox (version 2.14), but it also repros
with a copy of nm I built as part of a cross compiler (version 2.17 from FC6
64bit to AIX 5.3.0.0).
On Linux, even after a binary has been stripped, the dynamic symbols can still
be retrieved. The following commands show this with hello world:
[EMAIL PROTECTED] ~]$ gcc hello.c -o hello
[EMAIL PROTECTED] ~]$ strip hello
[EMAIL PROTECTED] ~]$ nm hello
nm: hello: no symbols
[EMAIL PROTECTED] ~]$ nm -D hello
w __gmon_start__
U __libc_start_main
U puts
[EMAIL PROTECTED] ~]$
On AIX, nm does not display these symbols, even though the native dump program
can still access them:
[EMAIL PROTECTED] ~]$ gcc hello.c -o hello
[EMAIL PROTECTED] ~]$ /opt/freeware/bin/nm hello | head
