but the problem with sets.c remains:

The MSDN help gives a simple example of code raising compiler error C2099:
// C2099.c
int j;
int *p;
j = *p;   // C2099, *p is not a constant

The example code shows to me, that there is a good reason  compiler
generates an error in that case.
j = *p; leads to an assignment of a random (and therefore maybe leading to a
non deterministic crash of the executable during runtime) value to a
variable, what can't be intended in a deterministic program.

Hope this helps.
