Problem with code written in IDE 1.5.7 on Arduino Leonardo and GSM Shield

Hi everybody,
I have a problem with IDE 1.5.7 on Arduino Leonardo and GSM shield.
If I used the example code of GSM library on IDE 1.0.5 it runs correct. Otherwise, when I try the same code on IDE 1.5.7 it doesn't work. Why?

Can someone help me please?

Otherwise, when I try the same code on IDE 1.5.7 it doesn't work. Why?

You need to come up with something a little less lame than "it doesn't work".

Does the code compile? Can it be uploaded? What EXACTLY happens when it runs?
