Subject: Re: Wrong child process exit status if core dump / seg fault

Hi Robert,

yes, I have tried all the methods. They return false or 0.

I assume that ($?.to_i >> 8) must be equal to ($?.exitstatus), but it 
doesn't.

As I can see in your tests, your exit codes are <= 255. In Windows exit 
codes are 32 bit, not only 8 bit (I am not sure about other platforms). 
I think this is the problem. In most cases the exit codes are < 255, so 
it fails only in rare cases...

Thank you for your help!
