=begin
Sometimes (about 30% times) when running the following code ruby crashes.

The code:

$threads_alowed = 750;
$threads = []
#Initializing thread objects
$threads_alowed.times{|thread_id|
$threads[thread_id] = {'thread' => Thread.new{}}
puts "thID #{thread_id} initialized"
}

def do_something(thread_id)
wait = rand(300)
print "\nThread #{thread_id} is doing something for #{wait} seconds"
sleep wait
end

while true do
$threads_alowed.times{|thread_id|
status = $threads[thread_id]['thread'].status
if status == false or status == nil
$threads[thread_id]['thread'] = Thread.new(thread_id){do_something(thread_id)}
print ","
end
}
print "."
sleep 0.03
end

The crash:

Tried Ruby 1.9.1 MinGW and mswin32 with the same result.

I could reach the the same crash with the following code:

somevar = []
700.times{|i|
somevar << Thread.new{}
puts "cycle #{i}"
}

Sometimes it crashes on the third time when I run the code, but sometimes it doesn't crash even if I run it 20 times.

Also able to reach the crash with:

700.times{|i|
Thread.new{}
puts i
}

and even with:

700.times{
Thread.new{}
puts "."
}

but not with:

700.times{
Thread.new{}
}

[Note: The script crashes even when 0 < i < 10]

do you get this on trunk?
=end

• Status changed from Open to Closed
• % Done changed from 0 to 100

=begin
Do you still get this with trunk (I will assume not since #2488 was fixed).
