(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. + + Fri Mar 14 12:07:46 2014 Zachary Scott <e@zzak.io> * doc/syntax/literals.rdoc: [DOC] Single quote strings allows escape |
