Can you attach the preprocessed source?

Created attachment 10956 [details]
compute_frame_pointer_to_cfa_displacement internal error source trigger

I have this same problem, only with Fedora Core 2/x86, building the cross-compiler for AVR as well.  gcc4.1 and gcc 4.03 both stop with this error.

I have attached the preprocessed source file resulting from the following command.

I gave up and deleted everything related.
I will see if I can re-create the environment again.

Can either one of you try the patch in PR 26015?

Hi, I have the same error.

I use  : 
 - binutils-2.16.1,
 - gcc 4.1.0,
 - avr-libc 1.4.3
But it works with gcc 4.0.3.

I use the doc : www.nongnu.org/avr-libc/user-manual/install_tools.html

Thanks a lot.

Putting

#define FRAME_POINTER_CFA_OFFSET(FNDECL) 0

as indicated in that patch, into config/avr.h seems to work, but it is also necessary to specify
--disable-libssp
to configure.

Perhaps libssp should by default be disabled for avr targets?

*** Bug 28273 has been marked as a duplicate of this bug. ***

Getting the same error when compiling gcc-4.1.1 on MacOSX for target avr. It was compiled with apple's XCode version of gcc which is gcc 4.0.1.

../configure --prefix=$PREFIX --target=avr --enable-languages=c,c++     --disable-nls --with-dwarf2

Same bug occures with 4.1.1 too, verified on an x86 and ppc host, cross compiling for Atmel AVR:
configure --target=avr --with-dwarf2
triggers the bug.

Confirmed.

AVR is not a primary or secondary platform.
