Bug ID: 64679
Summary: Spurious redefinition error when parsing
not-quite-most-vexing-parse declarations
Product: gcc
Version: 5.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: rs2740 at gmail dot com
Repro:
class Bar{
public:
Bar(int, int, int);
};
int main () {
int x = 1;
Bar bar(int(x), int(x), int{x});
}
gcc HEAD 5.0.0 20150119 (experimental) with g++ prog.cc -Wall -Wextra
-std=gnu++1y reports:
prog.cc: In function 'int main()':
prog.cc:8:24: error: redefinition of 'int x'
Bar bar(int(x), int(x), int{x});
^
prog.cc:8:16: note: 'int x' previously declared here
Bar bar(int(x), int(x), int{x});
With the last int{x} (note the braces) this cannot be a function declaration,
but g++ appears to emit the redefinition errors too early, before the full
declaration is parsed. Clang compiles this successfully.
