> Key: THRIFT-5461
> URL: https://issues.apache.org/jira/browse/THRIFT-5461
> Project: Thrift

> There's a bug in the Thrift Go generator that happens when an optional
> set<bynary> is used with a default value. For example, a simple struct like
> this:
> {code:java}
> struct OptionalSetBinary {
> 1: optional set<binary> bin = {}
> }
> {code}
> ...generates a default value like this:
> {code:go}
> var OptionalSetBinary_Bin_DEFAULT [][]byte = []string{
> }
> {code}
> ...and fails the compilation of the unit-test:
> {code:java}
> ../src/gen/thrifttest/ThriftTest.go:5620:5: cannot use []string{} (type
> []string) as type [][]byte in assignment
> {code}
