            Bug ID: 30209
           Summary: Inconsistency between lambdas' signatures and that of
                    the function they are in
           Product: gdb
           Version: 12.1
            Status: UNCONFIRMED
          Severity: normal

=3D=3D Input =3D=3D

$ cat x.cpp
#include <stdint.h>
static void ff(uint64_t b) { [&](){}(); }
int main() { ff(0); }
$ nm -C a.out | grep ff
0000000000401121 t ff(unsigned long)
0000000000401116 t ff(unsigned long)::{lambda()#1}::operator()() const
$ g++ x.cpp -g
$ gdb a.out
(gdb) b ff<TAB><TAB>

=3D=3D Observed =3D=3D

Tab completion yields:

ff(uint64_t)
ff(unsigned long)::{lambda()#1}::operator()() const

=3D=3D Expectation =3D=3D

ff(unsigned long)
ff(unsigned long)::{lambda()#1}::operator()() const

[or]

ff(uint64_t)
ff(uint64_t)::{lambda()#1}::operator()() const
