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
7 gethostbyname(name);
(gdb) step
