Problems with Data Types, High Severity (1)

libconfig.h
[+] struct config_list_t (1)

	Change	Effect
1	Field capacity has been removed from the middle position of this structural type.	1) Previous accesses of applications to the removed field will be incorrect. 2) Layout of structure fields has been changed and therefore fields at higher positions of the structure definition may be incorrectly accessed by applications.

Problems with Data Types, Medium Severity (2)

libconfig.h
[+] struct config_t (2)

	Change	Effect
1	Field error_file has been added at the middle position of this structural type.	1) Size of the inclusive type has been changed. 2) Layout of structure fields has been changed and therefore fields at higher positions of the structure definition may be incorrectly accessed by applications.
2	Type of field flags has been changed from int (4 bytes) to unsigned short (2 bytes).	This field may be incorrectly initialized or accessed by applications.
