Hi. Every time I try to read the flash in an xmega16-e5, I see avrdude crash:

    dima@shorty:~/stir/linbusctl$ avrdude -B8 -Pusb -c atmelice_pdi -p x16e5 -U flash:r:read.hex:i

    avrdude: AVR device initialized and ready to accept instructions

    Reading | ################################################## | 100% 0.13s

    avrdude: Device signature = 0x1e9445
    avrdude: NOTE: Programmer supports page erase for Xmega devices.
             Each page will be erased before programming it, but no chip erase is performed.
             To disable page erases, specify the -D option; for a chip-erase, use the -e option.
    avrdude: reading flash memory:

    Reading | ################################################## | 100% 2.80s

    avrdude: writing output file "read.hex"

    avrdude done.  Thank you.

    zsh: segmentation fault (core dumped)  avrdude -B8 -Pusb -c atmelice_pdi -p x16e5 -U flash:r:read.hex:i

This happens after the read completes, so fixing this isn't critically
important, but it's still not right. The core isn't particularly illuminating:

Recompile the avrdude package with debugging symbols:
https://wiki.debian.org/HowToGetABacktrace#Rebuilding_the_package_you.2BIBk-re_debugging
 
Then reproduce the bug. Also try passing -vvvv to avrdude.
