Now ruby can show static symbols on Linux though glibc's backtrace_symbols(3) don't show them. * addr2line.c (rb_dump_backtrace_with_lines): use dladdr(3) to detect what object file declares the symbol because dl_iterate_phdr can't detect the main executable file and codes on the stack. NOTE: signal trampolines sometimes on the user stack. (FreeBSD) * addr2line.c (rb_dump_backtrace_with_lines): stop showing backtrace if the function's name is main. NOTE: FreeBSD's backtrace (libexecinfo) shows _start and an additional address. Why it doesn't remove them on dladdr phase is, dladdr may fail to detect the main function but detect as _start function. Therefore it must be after scanning the symbol table and getting correct name. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@45335 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
