Bug ID: 91521
Summary: [9/10 Regression] expression incorrectly evaluated as
function with trailing return type
Product: gcc
Version: 9.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: aron.ujvary at nng dot com
Target Milestone: ---
As of g++ 8.3, the following code is well-formed:
struct foo {
int bar() { return 0; }
foo* operator->() { return this; }
};
int main()
{
int pt(foo()->bar());
return pt;
}
With g++ 9.1.0, 9.2.0, 10.0.0 20190822 (experimental), compilation fails with
"error: ‘parameter’ function with trailing return type not declared with ‘auto’
type specifier"
error message when compiling with c++11 or above, and with
"error: trailing return type only available with ‘-std=c++11’ or
‘-std=gnu++11’"
error message when compiling with c++03.
clang++ 8.0.1 also compiles this snippet just fine.
