--- Comment #2 from d.dorau at avm dot de --- (In reply to Eric Botcazou from comment #1) > Please post the output of 'gcc -v' for the affected compiler. We could reproduce this with several gcc builds of which I post the output below: 1. buildroot cross compile toolchain (which we used for bisecting) Using built-in specs.
