Bug ID: 71274
Summary: deprecated static const member of struct raises
warning without use
Product: gcc
Version: 6.1.1
Status: UNCONFIRMED
Keywords: diagnostic
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: vigerske at math dot hu-berlin.de
Target Milestone: ---
When compiling the code
struct foo
{
__attribute__ ((deprecated)) static const int a;
};
with GCC 6.1.1 (g++), it raises a deprecated-declaration warning:
dep.cpp:1:8: warning: ‘foo::a’ is deprecated [-Wdeprecated-declarations]
struct foo
^~~
dep.cpp:3:50: note: declared here
__attribute__ ((deprecated)) static const int a;
This is unexpected to me, as the documentation says that "The deprecated
attribute results in a warning if the variable is used anywhere in the source
file.". But it is not used anywhere.
