Problems with Data Types, Medium Severity (1)

rasqal.h
[+] struct rasqal_expression_s (1)

	Change	Effect
1	Field arg3 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.

Problems with Data Types, Low Severity (2)

rasqal.h
[+] enum rasqal_op (1)

	Change	Effect
1	Value of member RASQAL_EXPR_LAST has been changed from 33 to 34.	Applications may execute a wrong branch of code in the library and therefore change the behavior.
