Bingo! I'm back to my usual .data size when I compile with-mno-tablejump.
Should I fill a bug report? Is this a bug anyway? I think so since Ido not see why the array is built in ram, it should be in flash sinceall addresses are constants..

I'm not sure that it is a bug, per se. It's known that some swtichstatements get compiled into tables which can increase the size of the code.

Perhaps you could file an "enhancement request" to optimize that part ofAVR GCC. You fill out a bug report as usual, but you just change thecategory to enhancement.
