Hi all,

I recently bought a Micropendous board.. I'm now trying to have some
of the examples available to be compiled but they all fails with a
segmentation fault (See bottom of the mail).

I'm using avr-gcc 4.6.2 on a 64bit Archlinux. An example of such
firmware is VirtualSerial available from

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 http://sourceware.org/bugzilla/show_bug.cgi?id=13612 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 avr-libc.

Does the code need objects from avr-libc to link against?
Or can you get the bug without referring to libc?
