Bug ID: 113389
Summary: ICE when explicit object parameter is not declared as
the first parameter
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: cooky.ykooc922 at gmail dot com
Target Milestone: ---
Although it is obviously an error, it causes ICE:
struct A {
void foo(A, this A);
};
compiler output:
<source>:3:17: error: Only the first parameter of a member function can be
declared as an explicit object parameter
3 | void foo(A, this A);
| ^~~~~~
<source>:3:23: internal compiler error: Segmentation fault
3 | void foo(A, this A);
| ^
