--- Comment #46 from Artem S. Tashkinov <t.artem at mailcity dot com> --- (In reply to PeteVine from comment #44) > In case I was a little unclear, the board freezes, not the binary. Looks like GCC optimizes the output so much, the board cannot cope with such a perfect code. ;-) Jokes aside, I tend to believe that it's either a bug in the kernel or board components.
