Problems with Symbols, High Severity (1)

libjio.h, libjio.so
[+] jfsck ( char const* name, struct jfsck_result* res ) (1)

changed to:
jfsck ( char const* name, char const* jdir, struct jfsck_result* res )

	Change	Effect
1	Parameter jdir of type char const* has been added to the calling stack at the middle position.	Layout of parameter's stack has been changed and therefore parameters at higher positions in the stack may be incorrectly initialized by applications.

to the top

Problems with Data Types, Medium Severity (2)

libjio.h
[+] struct jfs (1)

	Change	Effect
1	Field jdir 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.
