Public bug reported:

Ubuntu 14.04.1 i386
avrdudude 6.0.1-1

I try to read EEPROM from Arduino board (ATmega328p) with USBtiny ISP
programmer.

FIRST
It crashed regularly. There is a report that free() detected memory allocation problem. EEPROM is empty, all 0xff; this can be important to replicate this crash.

# avrdude -c usbtiny -p m328p -U eeprom:r:xx.bin:r

avrdude: AVR device initialized and ready to accept instructions

Reading | ################################################## | 100%
0.01s

avrdude: Device signature = 0x1e950f
avrdude: reading eeprom memory:

Reading | ################################################## | 100%
17.15s

avrdude: writing output file "xx.bin"

avrdude: safemode: Fuses OK (H:05, E:DA, L:FF)

avrdude done.  Thank you.

*** Error in `avrdude': free(): invalid next size (normal): 0x093d5360 ***
Aborted (core dumped)


SECOND
When I write data to EEROM, it can be all 0xff, I read back different data and verification fails. It is good that it is detected but 100% of EEPROM is read to find that the first byte doesn't match. This can be improved, USBtiny is slow...

THIRD
Write data to EEPROM doesn't work, see previous point.
# avrdude -c usbtiny -p m328p -U eeprom:w:xx.bin:r

I tried USBasp programmer to the the same with Arduino and it works good
so my troubles are related to USBtiny programmer. I cannot say if
problem is in avrdude or in firmware of USBtiny programmer.
