Could anybody give some tips on it?
Some lines of code to reproduce the issue and a detailed description of
the problem (e.g. what is not working??) would be nice.
Take a look into the disassembled code (using avr-objdump). That may
give you some hints.

Very oddly, the code runs when I compile it with -O3, but not with any
other optimization level.
This works:
int main(void) {
uint8_t i;
for(i=1;i0xFF;i++) asm volatile(nop/n/t);
PORTA=0x01;
while(1);
}
You are using /n and /t instead of
Hello,
I recently tried to find out how the avr-gcc frame layout (stack layout)
looks like. I couldn't find any official documentation about this or is
there an *avr-gcc internals* manual I have not found yet?
I've created a figure [1] showing the stack after a CALL instruction and
how I think

- In which order is the return address saved on the stack?
This is the area where the AVR is big-endian (as Georg-Johann already
mentioned). To add to the confusion, the saved address could have
bits set that are not part of the PC

That's why I'm (desperately) hoping that the LTO project in GCC will
eventually help in this area.

Alternatively, an LLVM backend for AVR would give this capability
(approximately) for free.
I've started implementing an LLVM
