Bug ID: 103213
Summary: Lambda type name overlap
Product: gcc
Version: 11.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: mario.demontis at gmail dot com
Target Milestone: ---
/******************* BEGIN SOURCE *******************/
template<typename T>
struct Wrap{
T w;
};
int main() {
auto l1 = [x = 5](int a){return x+a;};
auto l2 = [y = 6](int a){return y+1;};
Wrap<decltype(l1)> w1{l1};
Wrap<decltype(l2)> w2{l2};
}
/******************** END SOURCE ********************/
Both w1 and w2 are assigned type name Wrap<main()::<lambda(int)> >
In gdb there is no way to distinguish between the 2 types:
(gdb) ptype 'Wrap<main()::<lambda(int)> >'
type = struct Wrap<main()::<lambda(int)> > {
struct {
int __x;
} w;
}
For the same reason, there is also no way to obtain the 2 different python
gdb.Type objects
