Most likely a compiler bug. Maybe you're being hit by
https://patchwork.kernel.org/patch/1438281/. Since you're using a Ti
DM3730, can you instead use the Linaro toolchains, that are also
pre-configured in Buildroot (just make sure you selected the Cortex-A8
architecture variant in Buildroot) ?

Thanks,

Thomas
