Recompile the avrdude package with debugging symbols:

Then reproduce the bug. Also try passing - to avrdude.


Bug#794043: avrdude: Segfault when reading an xmega16-e5 cpu

2015-07-29 Thread Dima Kogan
Package: avrdude
Version: 6.1-4
Severity: normal

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:
