I recently bought a Micropendous board.. I'm now trying to have some

I'm using avr-gcc 4.6.2 on a 64bit Archlinux. An example of such

What do you think?
As is it the linker that crashes and not the compiler: What version of
binutils do you use?
Does it work without relaxing?
It's binutils 2.22 and yes it's not shown when relaxing is not enabled.
It does look like a bug to me which I reported to
with a simple test case showing the issue.
Thanks for reporting.
But notice that binutils cannot chew C code. Maybe it's better to attach
the compiler output? Use -save-temps to get intermediate .s assembler
file. Better attach it together with the linker options you use.
Notice that binutils developers in general don't have AVR environment
installed or even know what "AVR" is; suppose it's a generic bug and
someone working for PowerPC would like to fix it.
The less barriers a bug report contains, the more likely someone will
take care of the bug; thus the report should not refer to avr-gcc or
Does the code need objects from avr-libc to link against?
Or can you get the bug without referring to libc?
