Summary: getdir crashes on windows (mingw)
Initial Comment:
I'm using a personally built version of Pd downloaded from CVS.  I needed the patch folder, so I compiled the [getdir] object, which works fine on Linux, but on Windows it crashes on [bang].
I looked at it a bit, but I'm at a loss to figure it out: It calls canvas_getdir(), which in turn calls canvas_getenv().  However, any attempt to dereference the pointer returned by canvas_getenv() causes a crash.
I inserted the following code into getdir_bang():
s = (t_symbol**)canvas_getenv(last);
    printf("[getdir] getenv: %#x\n", s);
    printf("[getdir] getenv->: %#x\n", (*s));
    printf("[getdir] getenv->s: %#x\n", (*s)->s_name);
It crashes on the second printf() statement, so the output is:
[getdir] getenv: 0x700a570
12 audio buffers
socket receive error: Unknown error (10054)
There may be something wrong with this pointer, but I cannot see what might be wrong.  It is in the g_canvas struct returned originally in getdir_new() by canvas_getcurrent().
