I'm not sure it's my setup, but since I upgraded to Cygwin 1.5.10-3 gdb
crashes when executing trivial calls to gethostbyname:
-------------------------------
$ gdb --args test/q

(gdb) r
Starting program: /home/em/KadC/test/q.exe
Program received signal SIGSEGV, Segmentation fault.
0xbff7a606 in KERNEL32!Heap32ListNext ()
from /cygdrive/c/WINDOWS/SYSTEM/KERNEL32.DLL
(gdb)
-------------------------------
The source code is very simple:
-------------------------------
#include <netdb.h>
#include <sys/socket.h>
int main(int ac, char *av[]) {
struct hostent *hp;
hp = gethostbyname("emnb");
return 0;
}
-------------------------------
After reinstalling 1.5.9-1 everything has gone back to normal.

---Type <return> to continue, or q <return> to quit---
Program exited normally.
(gdb)
-------------------------------
Strangely enough, no SIGSEGV seems to occur if I don't run gdb.
For the record, my Windows is an ancient Win98SE. The version of gdb
should be the latest; for some reason it identifies itself as
2003-09-20-cvs, although according to setup.exe it should be slightly
older, 20030919-1 (the other alternative offered is 20030303-1).
