Re: [Perfparse-users] Segmentation fault running perfparse

[Ben C. <Be...@cl...>]

Tim,

Oh dear, I've not seen this.

You are probably not the only person, just the only one who has come 
reported this problem.

Can I ask what system you are using, version of MySQL, OS version etc.

My suspicion is that your version of the MySQL client libs is different 
from the MySQL server.  Possibly you have two versions of the client 
libs in different directories.  Can you check this first of all?

You are a lot closer to the problem than us.  Since it works perfectly 
with us.  If there is anything else you can do to find the exact line 
which causes the failure, it would be of great interest.

Regards,

Ben Clewett.
