The sizeof operator, when applied to a parameter declared to have array,
yields the size of the adjusted (pointer) type, even if the parameter
declaration specifies a length.

Could it be compiler specific? It is working fine for me
Test]$ cat sizeof.c

#include <stdio.h>
#define NUMFIELDS 10
main()

char *fields1[NUMFIELDS];
char fields2[NUMFIELDS];
