[avr-libc-dev] WinAVR - gcc 3.4.6 - AVR Studio - DuoCore PC - Stackpointer problem

[Steffen Rose]

Hello,

our program works compiled with cygwin, Makefiles and WinAVR 
works correctly compiled on different PCs. But on ony System we 
have the following problem:

The PC is a DuoCore PC and we use the IDE AVR Studio for 
compiling. The used Options are the same than the Makefile. 
Additional Options are used for creating needed Files for the 
AVR Studio (-M -MD ..).

Now, we can see corrupt code on different positions. With minimal 
changes the error is on a total other place. On the one time the 
wrong parameters from the Stack frame is used. One time the 
Stackpointer High-byte is set to 0x00.

Have anyone help for me?
