=begin
I am using the serialport 1.0.4 Ruby gem. In my serial port connection code, I have the following piece of code [1] that causes Ruby to crash from time to time.

[1] In serial_equipment_connection.rb
23 status = Timeout::timeout(timeout) {
24 while (!listener.match)
25 sleep 0.5
26 end
27 }

ruby –v
ruby 1.9.1p378 (2010-01-10 revision 26273) [i386-mingw32]

I am running on a Windows XP SP 3 machine.

I have attached the two related files - serial_equipment_connection.rb, equipment_connection.rb, and the crash log.

[2] Crash log (file attached)

MXP>(eval):2: [BUG] The handle is invalid.

Is this reproducible on Ruby 1.9.2?

I see a crash in 1.9.2p0 also, although from the stack trace it looks like the crash does not occur at the same place in the code

Hi Elvita, sorry for late response. We're planning 1.9.3 release soon and we want to know if it still causes SEGV or not.

I installed RubyInstaller (ruby 1.9.2p180 (2011-02-18) [i386-mingw32]) and DevKit on Windows 7 64bit, then installed serialport 1.0.4 by a gem. For this env, basic serialport communication looks working.

Can you show us a way to replicate the bug on our side?

Usa, can you take at look at this? If 'Feedback' is enough, reassign to me.

This is a 3rd party issue, I guess.
