Aparent connection lost resulting in crash

[Julien Chavanton]

When there is a problem with a connection the next time we call a
function like mysql_query() or mysql_ping() it does report an error
witch is fine but if I call

2 function in a row before reseting the connection the function crash
instead of reporting an error, I can leave with that.

 

Now when a connection is left idle for some time and is probably
disconnect if I call mysql_query() it does crash instead of reporting an
error.

 

How can I validate this properly or handle it correctly?
