Bug ID: 116584
Summary: Type/value mismatch confuses error recovery
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: blubban at gmail dot com
Target Milestone: ---
template<typename T> struct foo;
void* bar()
{
return (decltype(foo<5>)*)5;
}
No flags needed.
Result:
<source>: In function 'void* bar()':
<source>:5:31: error: type/value mismatch at argument 1 in template parameter
list for 'template<class T> struct foo'
5 | return (decltype(foo<5>)*)5;
| ^
<source>:5:31: note: expected a type, got '5'
<source>:5:17: error: expected primary-expression before 'decltype'
5 | return (decltype(foo<5>)*)5;
| ^~~~~~~~~~~~~~~~
<source>:5:17: error: expected ')' before 'decltype'
5 | return (decltype(foo<5>)*)5;
| ~^~~~~~~~~~~~~~~~
| )
Compiler returned: 1
Expected: Just the first error, the last one looks like it's telling me to
write return ();
Diagnostics are even funnier if colored - in the last one, the first letter of
decltype is red, while the ecltype is green. https://godbolt.org/z/7bcazrPsY
