Hi Dave,
The newly modification of gdb involved some bug. When using mount,
crash prints the following message.
<cut>
crash> mount
mount: invalid structure member offset: mount_mnt_devname
FILE: filesys.c LINE: 1396 FUNCTION: show_mounts()
[./crash] error trace: 45dbf7 => 49dc02 => 49af31 => 502cdd
MOUNT SUPERBLK TYPE DEVNAME DIRNAME
502cdd: OFFSET_verify+189
49af31: show_mounts+785
49dc02: cmd_mount+1234
45dbf7: exec_command+919
mount: invalid structure member offset: mount_mnt_devname
FILE: filesys.c LINE: 1396 FUNCTION: show_mounts()
crash>
<cut>
Then I try to find what caused the bug. I found a wrong number is returned
when using "STRUCT_SIZE_INIT(mount, "mount");".
and then I referred to the changelog to see what had happened, and I guess
from changelog, the bug is related to
<cut>
- Patch to the internal gdb_get_datatype() function to return the
typecode and length of integer variables.
(adrian.wenl@xxxxxxxxx, anderson@xxxxxxxxxx)
<cut>
So I made the patch to fix it.
