gccgo rejects to compile the following program:

package a
var a, b = 0, a^0/8i
go.go:2:15: error: incompatible types in binary expression

Both gc and go/types compile it.

gcc version 6.0.0 2015070 (experimental) (GCC)

compiler: Use context to determine types of complex expressions.
abd26de 
    
    When determining the type of a complex expression, it is important
    to recognize cases where a complex value can be represented as a
    real number.
    
    Fixes golang/go#11572.
