Bug #12302

Updated by nobu (Nobuyoshi Nakada) over 8 years ago

~~~ruby ~~~ 
 at_exit do 
   puts "1 #{$!}" 
 end 

 at_exit do 
   puts "2 #{$!}" 
   raise 'x' rescue nil 
 end 

 at_exit do 
   puts "3 #{$!}" 
   exit 1 
 end 
 ~~~ 

 Nr 3 runs first and exits 1 ... Nr2 receives the correct exit status ... but using raise/rescue there overrides `$!` $1 and Nr 1 thinks it is a clean exit ... 

 seems semi related to https://bugs.ruby-lang.org/issues/5218 ... ideally the `at_exit` at_exit block should restore the previous `$!` $! ... or give some other way of knowing the exit status like passing it to the block 

 ~~~ruby ~~~ 
 at_exit do |exception| |exception} 
    ... 
 end 
 ~~~
