The first release of RIOT 1.x contained code compiled with an enhanced instruction set (AVX2). It seems that there are still some older CPUs out there which do not support this.
If you got a crash at program startup or at runtime, upgrade to version 1.0.1 which should solve this because it uses the SSE2 instruction set, normally available on all 64bit CPUs
