 >     warning: .dynamic section for "/lib/libc.so.6" is not at the expected address (wrong library or version mismatch?)
 >     warning: .dynamic section for "/lib/ld-linux.so.2" is not at the expected address (wrong library or version mismatch?)
 >     warning: .dynamic section for "/lib/libanl.so.1" is not at the expected address (wrong library or version mismatch?)
 >     warning: .dynamic section for "/lib/libdl.so.2" is not at the expected address (wrong library or version mismatch?)
 >     warning: .dynamic section for "/lib/libpthread.so.0" is not at the expected address (wrong library or version mismatch?)
 >     warning: .dynamic section for "/usr/lib/libz.so.1" is not at the expected address (wrong library or version mismatch?)
 >     warning: .dynamic section for "/lib/libnss_files.so.2" is not at the expected address (wrong library or version mismatch?)

 >     warning: Could not load shared library symbols for 17 libraries, e.g. [...]
 >     Use the "info sharedlibrary" command to see the complete listing.
 >     Do you need "set solib-search-path" or "set sysroot"?

 > In contrast, the '-ix' option will load the specified gdbinit file _before_
 > parsing object/core files. This will remove said warnings.
