Problem with SIGSEVG on free_form() call...

Hi all,

I'm very much a newbie to ncurses programming.

I'm running ncurses 5.7.3 on Oracle Linux 6.4.

I'm a bit baffled, as I'm getting a SIGSEV on a free_form() call.  I'm definitely calling it on a valid form.

Here's what I'm seeing when I run through gdb:
Program received signal SIGSEGV, Segmentation fault.
0x00007ffff7de7d94 in Disconnect_Fields (form=0x4019e5) at ../../form/frm_def.c:129
129      for (fields = form->field; *fields; fields++)
(gdb) backtrace
#0  0x00007ffff7de7d94 in Disconnect_Fields (form=0x4019e5) at ../../form/frm_def.c:129
#1  0x00007ffff7de7e15 in free_form (form=0x4019e5) at ../../form/frm_def.c:343
#2  0x00000000004017fd in main (argc=1, argv=0x7fffffffe508) at ncurses_form.c:209

Is this a known bug?  Am I just an idiot? :-)

As I said, I'm still very new to programming ncurses, and I'm afraid it's something blindingly obvious, but, I'm just not seeing it.

Thanks,

-Mark
