---------------------------------------
Also, why close the bug before you understand the intent of the bug?

> Key: THRIFT-3472
> URL: https://issues.apache.org/jira/browse/THRIFT-3472
> Project: Thrift
> Issue Type: Bug
> Affects Versions: 0.9.2
> Environment: Ubuntu 14.04.3 LTS x86_64
> Reporter: Jason Heimann
>
> The following erroneous IDL was fed into thrift, from which we generated
> python (new_style), java (private-members), node.js and C++ output:
> {code}
> namespace java com.acme.model.sequencenumber
> namespace py acme_thrift.model.sequencenumber
> namespace cpp acme.model.sequencenumber
> include "Common.thrift"
> struct SequenceNumberResponse
> {
> 1: required Common.ResponseContext context;
> 2: required Common.VersionId sequenceNumber
> }
> {code}
> Each of these generated languages are compiled (as applicable) and packaged
> after generation. This is all to say, several revisions of our thrift IDL
> successfully generated, compiled, packaged and deployed with this error.
> ...until it didn't. An IDL revision in a completely unrelated namespace
> triggered the following compilation error in the C++ output:
> {code}
> In file included from
> /build_tmp/thrift-api-cmake/generated-sources/gen-cpp/SequenceNumber.cpp:7:0:
>
> /build_tmp/thrift-api-cmake/generated-sources/gen-cpp/SequenceNumber.h:18:57:
> error: 'acme::model::sequencenumber' has not been declared
>
> /build_tmp/thrift-api-cmake/generated-sources/gen-cpp/SequenceNumber.h:18:95:
> error: expected ',' or '...' before '&' token
> {code}
> Of course, adding the missing semicolon fixed this issue. This being said,
> I'd expect something in the thrift compiler to complain about such faulty IDL
