struct_stat.h
[+] struct stat 7

	Change	Effect
1	Size of field st_ctim has been changed from 8 bytes to 16 bytes.	1) Size of the inclusive type has been changed. 2) Previous accesses of applications and library functions to this field and fields at higher positions of the structure definition may be broken.
2	Size of field st_mtim has been changed from 8 bytes to 16 bytes.	1) Size of the inclusive type has been changed. 2) Previous accesses of applications and library functions to this field and fields at higher positions of the structure definition may be broken.
3	Size of field st_atim has been changed from 8 bytes to 16 bytes.	1) Size of the inclusive type has been changed. 2) Previous accesses of applications and library functions to this field may be broken.
4	Type of field __st_ino has been changed from __ino_t (4 bytes) to __ino64_t (8 bytes).	1) This field may be incorrectly initialized or accessed by applications. 2) Size of the inclusive type has been changed.
5	The relative position of field st_ino has been changed from 13 to 1.	1) Applications will access incorrect memory when attempting to access this field. 2) Size of the inclusive type has been changed.
6	Field __pad1 has been removed from the middle position of this structural type.	1) Layout of structure fields has been changed and therefore fields at higher positions of the structure definition may be incorrectly accessed by applications. 2) Size of the inclusive type has been changed.
7	Field __pad2 has been removed from the middle position of this structural type.	1) Layout of structure fields has been changed and therefore fields at higher positions of the structure definition may be incorrectly accessed by applications. 2) Size of the inclusive type has been changed.

[+] struct timespec 1

	Change	Effect
1	Type of field tv_sec has been changed from __time_t (4 bytes) to __time64_t (8 bytes).	1) Size of the inclusive type has been changed. 2) Previous accesses of applications and library functions to this field and fields at higher positions of the structure definition may be broken.

Problems with Data Types, Low Severity 3

struct_stat.h
[+] struct stat 1

	Change	Effect
1	Size of this type has been changed from 104 bytes to 112 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

Field 'retval.constructor_chain.relent.sym_ptr_ptr.the_bfd.xvec._bfd_stat_arch_elt.p1' in the return value has base type 'struct stat'.

struct_timespec.h
[+] struct timespec 2

	Change	Effect
1	Size of this type has been changed from 8 bytes to 16 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.
2	Type of field tv_nsec has been changed from __syscall_slong_t to long.	Replacement of the field data type may indicate a change in the semantic meaning of the field.

[+] affected symbols: 1 (9.1%)

_bfd_std_section [data]

Field 'retval.constructor_chain.relent.sym_ptr_ptr.the_bfd.xvec._bfd_stat_arch_elt.p1.st_atim' in the return value has base type 'struct timespec'.
