A value_string array *must* be terminated with an end-of-list entry:
static const value_string msgtypenames[] = {
{ 0x10, "Type 16" },
{ 0x01, "Type 1" },
{ 0x03, "Type 3" },
{ 0x05, "Type 5"},
{ 0, NULL }
};
Otherwise, code in Wireshark might run past the end of the array and
refer to data that's not part of the array as if it were part of the
array, which can, for example, cause non-pointer data to be
dereferenced as if it were a pointer.
There's nothing Windows-specific about that; if it worked on some
other operating system, that was purely by luck.
