Glibc detected - mySQL error?

I’m trying to get Radiant intalled on my Site5 account. During the
initial ‘rake production db:bootstrap’ task I kept getting this error
message:

*** glibc detected *** double free or corruption (fasttop): 0x08233108


Aborted (core dumped)

I ended up using phpMyAdmin to setup the database, but the app
wouldn’t start. For testing, I tried a ‘ruby script/server’ and got
the same error message.

I submitted a ticket to Site5 and their response was, “Having
performed a search online this error is most commonly experienced as a
result of the way in which the task or application interfaces with
MySQL itself. I would advise consulting with the application vendor
for further assistance if required.”

Does anyone know what this glibc error means?
