Bug ID: 63377
Summary: Bad diagnostic - "expected unqualified-id" instead of
"no type named __ in namespace"
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: b_filip at zoho dot com
Here is a simple code that reproduces the problem, clang reports the error much
better:
temp@host $ cat gcc_clang_example.cpp
#include <iostream>
int main() {
try {}
catch (const std::invalid_argument&) {}
}
temp@host $ g++ gcc_clang_example.cpp
gcc_clang_example.cpp: In function ‘int main()’:
gcc_clang_example.cpp:5:39: error: expected unqualified-id before ‘&’ token
catch (const std::invalid_argument&) {}
^
gcc_clang_example.cpp:5:39: error: expected ‘)’ before ‘&’ token
gcc_clang_example.cpp:5:39: error: expected ‘{’ before ‘&’ token
gcc_clang_example.cpp:5:40: error: expected primary-expression before ‘)’ token
catch (const std::invalid_argument&) {}
^
gcc_clang_example.cpp:5:40: error: expected ‘;’ before ‘)’ token
temp@host $ clang++ gcc_clang_example.cpp
gcc_clang_example.cpp:5:23: error: no type named 'invalid_argument' in
namespace 'std'
catch (const std::invalid_argument&) {}
