I have setup my Eclipse/GNU toolchain using the Lynch tutorial. It assembles, compiles and links fine but then I get a series of windows error messages:
cc1.exe application error
The instruction at 0x… referenced memory at 0x… The memory could not be “read” etc etc
Any ideas?

Hello Rich,
please check if you have more than one cygwin1.dll on your pc.
Perhaps this is the problem.
Btw, if you like to have a toolchain without the need of
Cygwin, take a look here:
You will find some tutorial here too.

That’s it! Thanks. The duplicate Dlls come from a WinAVR installation.
I have removed the cygwin1.dll from the WinAVR\bin directory and all is well. WinAVR still compiles and the errors from eclipse are gone. Of course I would like to understand what is REALLY going on so I can sort of paths etc.

Hi Rich,
Cygwin is very sensitive about different dll’s.
Some application comes with his own cygwin.dll’s, which
is not a good bearing. But the problem is, if the applications
does not have the dll’s. The user must download and install
the Cygwin packages, which is big.
This is the “hen-egg” problem 
More information you can find at the cygwin page:
