Bug ID: 67013
Summary: Compilation error for well-formed program with empty
declaration in the global namespace
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: anders.granlund.0 at gmail dot com
Target Milestone: ---
Consider the following program:
int main() {};
It is well-formed, the extra semi colon is just an empty declaration after the
definition of main.
Compile it with the following command line:
g++ prog.cc -std=c++14 -pedantic-errors
The following error message is then given:
prog.cc:1:14: error: extra ';' [-Wpedantic]
int main() {};
^
I expected to get no error messages since the program is well-formed. For
comparison Clang gives no error message.
I have tried it with gcc HEAD 6.0.0 201507 here:

--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Did this change between C++98 and C++14 because GCC has the following in its
source:
/* A declaration consisting of a single semicolon is
invalid. Allow it unless we're being pedantic. */

--- Comment #2 from Anders Granlund <anders.granlund.0 at gmail dot com> ---
That comment seems to be incorrect. The c++ standard has never forbidden empty
declarations at global namespace. I think we should get a warning instead of an
error.

It might have changed between the ARM and C++98, but I haven't checked.

Is ARM a c++ standard before c++98?

It is the C++ Annotate Reference Manual. It was not exactly a standard but it
was what described C++ before the standard came around.

To some extend this could be considered a regression if it is a true bug as
GCC's old parser did not error out about this.

Fixed in GCC 11+, even though this is an older bug report of the problem, PR
96068 already has the reference to the commit message and all so closing as a
dup of that bug.
*** This bug has been marked as a duplicate of bug 96068 ***
