Bug #9568
Ruby interpreter crashes when executing a script in debug mode
Description
The following script will crash the ruby interpreter when ruby is run in debug mode.
This script is creating mock HTTP objects and creating the Response class out of the middle of the Savon gem and calling a private method in a very odd way because it is a reduced test case pulled from a much larger script. The actual script use Savon in a much more conventional way:
-- crash_example.rb --
require 'savon'
class SampleHTTPStuff
def error?
return true
end
def code
return 500
end
def body
return %q{<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"><SOAP-ENV:Body><SOAP-ENV:Fault><faultcode>SOAP-ENV:Server</faultcode><faultstring>Internal Error</faultstring></SOAP-ENV:Fault></SOAP-ENV:Body></SOAP-ENV:Envelope>}
end
end
http = SampleHTTPStuff.new()
response = Savon::Response.new(http, {}, {})
begin
response.instance_eval { raise_soap_and_http_errors! }
rescue => e
puts "Ouch!"
end
--- end of crash_example.rb
For what it's worth, I'm using version 2.3.3 of the Savon gem.
If I run this using:
ruby -d crash_example.rb
I get a segmentation fault error. The problem appears to be the result of calling vm_throw with the "throwobj" having the value 0x8
If I run the script without the "-d" debug flag, the script runs without trouble.
I am running this on Mac OS X 10.9.1 on a MacBook Pro Retina 15"
using RVM I have tried the same code on 2.0, 2.1, and the 2.2dev head (as of 2/25/2014). They all exhibit the same behavior
I've attached a transcript file of the code being run.
