After upgrading to Ruby 1.8.4 I started getting this error message:

glibc detected \*\*\* /usr/bin/ruby: corrupted double-linked list:  
0x0a6d8540

* * *

I am running Ruby 1.8.4, Ruby on Rails 1, Fedora Core 4.

Any ideas why this is happening?

Thanks,

I am using the same setup, and I don’t get this error message. Can you  
extract some code, that produces this error?

Best regards,

Oliver, I fixed the problem. I had to update my Dev. Tools group and  
rubygems.

thanks,
