On cygwin, with the new charset support, I get this:
(top-gdb) whatis L""
type = wchar_t [1]
(top-gdb) ptype wchar_t
type = short unsigned int
This is correct. wchar_t is 16-bit on Windows.
(top-gdb) ptype L""
type = short unsigned int [1]
(top-gdb) ptype L"a"
type = short unsigned int [3]
(top-gdb) ptype L"aa"
type = short unsigned int [5]
(top-gdb) ptype L"aaa"
type = short unsigned int [7]
(top-gdb) ptype L"aaaa"
type = short unsigned int [9]
Notice how the size of the array grows 1,3,5,7,9,...
GDB was linked with the real iconv.
On x86_64-linux, I get:
(top-gdb) ptype L""
type = int [1]
(top-gdb) ptype L"a"
type = int [2]
(top-gdb) ptype L"aa"
type = int [3]
(top-gdb) ptype L"aaa"
type = int [4]
(top-gdb) ptype L"aaaa"
type = int [5]
