Thread model: posix
gcc version 8.3.0 (Debian 8.3.0-3)
Command line which causes the problem:
g++ temp_namespace_anonymous.cpp
RESULT OF THE CALL:
namespace_anonymous_1_min_ok.cpp:14:8: warning: ‘Node’ has a field
‘Node::receiverQueue’ whose type uses the anonymous namespace
[-Wsubobject-linkage]
struct Node
File temp_namespace_anonymous.cpp is generated as follows:
g++ -E namespace_anonymous_1_min_ok.cpp > temp_namespace_anonymous.cpp
HOWEVER output of
g++ namespace_anonymous_1_min_ok.cpp
is OK
You will find file
namespace_anonymous_1_min_ok.cpp
(which can also be considered as .ii file)
attached to this report.
