[previous] 0675 [next] [C] Initializer is not of compatible 'struct'/'union' type.
Constraint violations REFERENCE - ISO:C90-6.5.7 Semantics, ISO:C90-6.3.16.1 Simple Assignment - Constraints

This is a constraint error

A 'struct'/'union' has been initialized with an expression of incompatible type. The initializer must be an expression of the same 'struct'/'union' type. For example:
