Bug ID: 67065
Summary: Missing diagnostics for ill-formed program with main
variable instead of function
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: ---
The following program is ill-formed (proc.cc):
int main;
Compile it with the following command line:
clang++ prog.cc -std=c++14 -pedantic-errors
No error messages are given. Since the program is ill-formed I expected to get
at least one error message.
The program is ill-formed by following sentence in [basic.start.main]p3
(http://eel.is/c++draft/basic.start.main#3):
"A program that declares a variable main at global scope or that declares the
name main with C language linkage (in any namespace) is ill-formed."
I have tired this with gcc HEAD 6.0.0 20150729 here:
