CoapBlip ip_malloc_init dangerous relocation: unaligned address (using mspgcc4.7)

[GoogleCodeExporter]

What steps will reproduce the problem?
1. msp430-gcc (GCC) 4.7.0 20120322 (mspgcc dev 20120911)
2. cd /opt/release_tinyos_2_1_2/apps/CoapBlip ; make z1 blip coap

What is the expected output? What do you see instead?
expected: compilation of apps/CoapBlip

What did I see:
pdemil@Beaumon:/opt/release_tinyos_2_1_2/apps/CoapBlip$ make z1 blip coap
mkdir -p build/z1
