I get the same. Maybe a bug that was introduced recently?

(gdb) list
1       #include <stdio.h>
2       #include <netdb.h>
3
4       int main(int argc, char *argv[])
5       {
6               char name[] = "localhost\0";
7               gethostbyname(name);
8               printf("Hello, world\n");
9
10              return 0;
(gdb) break 7
Breakpoint 1 at 0x4010bc: file test.c, line 7.
(gdb) run
Starting program: /cygdrive/c/shared/test/a.exe

Breakpoint 1, main (argc=1, argv=0xa0521d0) at test.c:7
