Bug #6558
closed
Crash in garbage collection - using caller inside finalizer method
Description
While debugging a hangup in a daemon, created the following program that crashes intermittently in 1.9.1 and 1.9.2 (don't have a current 1.9.3), and finishes in 1.8 (ruby 1.8.7 (2012-02-08 patchlevel 358) [i686-linux]):
====== infinite.rb
def foo
x = "hello world"*100000
ObjectSpace.define_finalizer(x, lambda { |x| recurse(1000);print "x: "+caller[1]+"\n"})
x = nil
end
def recurse(n)
y="hello world"*1000
ObjectSpace.define_finalizer(y, lambda { |x| print "y: "+caller[1]+"\n" })
y = nil
n>0 ? recurse(n-1): nil
end
500.times do |i|
foo
end
puts "done"
The host machine is running Red Hat Enterprise Linux Server release 5.3 (Tikanga).
The program isn't deterministic - usually it crashes, sometimes not.
In 1.9, even when it finishes it's still got a problem: the number of output messages is less than the number of finalizers that should run. Running it via
ruby infinite.rb | sort | uniq -c
gets results like:
1 done
496 x: infinite.rb:2:in foo' 2 x: infinite.rb:8:in recurse'
105214 y: infinite.rb:2:in foo' 359123 y: infinite.rb:8:in recurse'
19099 y: infinite.rb:9:in block in recurse' 999 y: infinite.rb:9:in new'
2004 y: infinite.rb:9:in print' 12013 y: infinite.rb:9:in recurse'
The number of "x: infinite" messages adds to 498 (496+2), rather than the expected 500. The number of "y: infinite" messages adds up to 498452 instead of the expected 500,000.
========== Trace from crashing run

It does not crash for me using Ruby 1.9.3p0. I've also added a thread on top of the above script:
Thread.new do
loop do
sleep 0.01
GC.start
end
end
I use it to force GC and detect C extensions errors. As said before, I cannot reproduce the crash in 1.9.3p0.

Ummm.. I can't reproduce SEGV in trunk.
Please reopen this ticket if you reproduce it.
Thanks.
