--- Comment #6 from Martin Liška <marxin at gcc dot gnu.org> ---
I'm woried that both reduced code snippets are an invalid code (at least clang
rejects that).
I reduced that to a valid test-case:
$ cat gcc_segfault_repro.ii
class Lockable {
public:
Lockable(int *);
};
template <typename> class ThreadTask2 {
Lockable _state_mutex{[]() -> int * { static int srcloc; return 0; }()};
public:
ThreadTask2() {}
};
void x() { ThreadTask2<int> foo; }
$ g++ gcc_segfault_repro.ii -c
gcc_segfault_repro.ii: In instantiation of ‘ThreadTask2<
<template-parameter-1-1> >::ThreadTask2() [with <template-parameter-1-1> =
int]’:
gcc_segfault_repro.ii:10:29: required from here
gcc_segfault_repro.ii:6:52: internal compiler error: Segmentation fault
6 | Lockable _state_mutex{[]() -> int * { static int srcloc; return 0;
}()};
