avrdude version 6 series fails to write programs bigger than 131.072 bytes to flash on my atxmega256a3bu. Instead of continuing onwards from the 131.072 byte (128kb) mark, the write procedure loops back to 0x0000, corrupting data from there on.

Or to put it an another way: When I flash a program 130kb in size, I end up with 128k of data in my flash, whereof the first 2kb is corrupted.

This problem was introduced in the version 6 series of avrdude (I tried 6.0.1, 6.1, 6.1-svn-20131205 and 6.2). Version 5.11 works fine for me.

No errors show up during writing, the bug manifests itself during verification and of course execution of the program, as the mangled program crashes the MCU.

Curiously this 128k mark is exactly on the second time an offset is defined in my intel .hex file. To rule out problems with the file reader code for that format I also tried .srec and .elf; same result for all.
