I have screwed up my cygwin env enough on my windows machine so that irb  
will consistently crash with no visible errors or messages.

Does anyone knows where I can look to get info about the crash ie core  
file  
location or crash log ?

In irb \> require ‘RMagick’. Boom irb crash no messages ?

Thanks you all !!

If I understand correctly you’re looking for a coredump. Many times  
you have to run ‘ulimit -c unlimited’ in order for a coredump to be  
generated. That is using Bash, not sure about others. Also not sure  
if that applies to Cygwin either.

Hope that helps.
