Hi,

I just checked my skin with Valgrind CVS and Suse 9.0,
and now I have the problem that the skin doesn't generate
dumps any more.

I have in SK_(post_clo_init):

...
    VG_(sprintf)(filename, "%s.%d", dump_file_base, VG_(getpid)());
    fd = VG_(open)(filename, VKI_O_WRONLY|VKI_O_TRUNC, 0);
    if (-1 == fd) { 
	fd = VG_(open)(filename, VKI_O_CREAT|VKI_O_WRONLY,
		       VKI_S_IRUSR|VKI_S_IWUSR);
	if (-1 == fd) {
	    file_err(); 
	}
    }
    VG_(close)(fd);
...

to truncate/create the dump file.
With strace, I see this for this part of code:

getpid()                                = 13270
open("/home/weidendo/dumps/cachegrind.out.13270", O_WRONLY|O_TRUNC) = -1 
ENOENT
(No such file or directory)
close(-2)                               = -1 EBADF (Bad file descriptor)

Obviously, strace correctly gives back -1 for
	fd = VG_(open)(filename, VKI_O_WRONLY|VKI_O_TRUNC, 0);
but my skin gets -2 (Ok, that's a small bug to call close(-2), but still...).
But it should get -1, too ?!?

Josef
