memcpy causes FaultISR

hello,

this litlle code causes a FaultISR calling memcpy().

I'm using CCS6, TM4C1294KCPDT, Compilerversion TI v5.2.6, TivaWare_C_Series-2.1.1.71.

Any idea ? (with another data structure memcpy works correct...)

For me, this looks like an error in the library or compiler/linker.

Thanks !
