Yes. Thank you for all the replies. I finally tried Carlo's patch with the 
Intel compiler and it also produces now the corresponding warning:

bug.c(7): warning #144: a value of type "int *" cannot be used to initialize 
an entity of type "long *"
        CFG_SIMPLE_INT("b", &a[0]),

I think this warning is sufficient to see that something might go wrong at this
