Thanks for reporting stuff like this, but really, this format of
reporting bugs is horrible, it does not contain any hints as to what you
were doing, nor how to reproduce it at all.

What am I supposed to do with this?  How do I know if this bug is ever
resolved?  When did it show up?  What workload caused it?

A strace really doesn't help much here, do you have a reproducer?

thanks,
