--- Comment #2 from marcus at jet dot franken.de 2011-03-24 09:58:48 UTC ---
there is a malloc(sizeof(struct1)+sizeof(struct2))
and the struct 1 has 

uint8_t data[0] 
at the end, where struct2* = struct1*->data;

the malloc() seems to allocate insufficient memory, spo the overflow checker
triggers.
