save() freezes

So far, I have used it with the latest official firmware version.
With the cutting edge build I now got:

ERROR: Too big to save to flash (22197 vs 20480 bytes)

This is better as it does not crash and gives me information about how much smaller the code must be.

I can use the save on send option "Direct to Flash" then. However, the code will be interpreted slightly different in that case (as also mentioned here).

Thanks for the hint about the latest version. While it doesn't fix the problem it gave me an idea what is wrong.
