And just to add on that sometimes the access violation occurs even no resultant
datatype conversion occurs, for example:

void foo(void); // even this kind of functions gives access violation

and the JVM gets halted because of this access violation during the execution of
such method. But the problem is that I don't seem to find any problems when
calling these kinds of methods from C, not error, no warning, nothing at all. So
why JVM is halted? This kind of function signature doesn't have a parameter or
return value.
