Description Stan Cox 2012-03-12 11:27:06 UTC 
The .library probe modifier is not always aware of an executables rpath, which is set via ld -rpath

.library is aware of rpath in iterate_over_libraries
query_module
 sdt_query::handle_query_module
 iterate_over_notes
 sdt_query::handle_probe_entry() 
 iterate_over_modules 
 query_module 
 iterate_over_libraries

however it is not aware earlier at
dwarf_builder::build
 calls find_executable (user_lib, "LD_LIBRARY_PATH") 
  which doesn't check rpath 
 dwarf_builder::get_user_dw
 sdt_query;iterate_over_modules->dwfl_getmodules
  doesn't find e.g. /.../.../libperl only libperl
