Another data point:

By chance, I was just now looking at a problem where my mysql 51 client core-
dumps on exit but only if I have LC_CTYPE=en_US.UTF-8 in my environment.

The back trace is:

Core was generated by `mysql'.
Program terminated with signal 11, Segmentation fault.

This is on a recent current amd64 and the issue has been present for a while.
