[avrdude-dev] [bug #15162] Butterfly support in version 5.0 is broken

[Nick Lott]

Follow-up Comment #2, bug #15162 (project avrdude):

Hi I've tested the changes but I have a slightly different problem. I'm
running OsX Tiger 10.4.3 and avrdude5.0-beta works with the butterfly.
Version 5.0 segfaults when it attempts to write to the butterfly. Below is
the output and the crash report. This was using a fink install (package info
from http://screwdecaf.cx/tools.html). I've tried recompiling from the latest
CVS source but I get the same problem. 
 
There are 31 Differences between the 2 versions of butterfly.c any idea where
to start looking? Most of the changes appear to be castings. If I use the new
butterfly.c with the Beta version it seems to work fine so the problem might
be due to changes elsewhere in the program.
 
Any ideas? Can anyone replicate this problem?
