Bug ID: 113598
Summary: GCC internal compiler error
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: jlame646 at gmail dot com
Target Milestone: ---
GCC rejects the following valid program. https://godbolt.org/z/zr1MbP1r7
```
#include <functional>
#include <cstdint>
using namespace std;
class Cpu
{
private:
typedef uint8_t(Cpu::*OpCode)();
OpCode *op_codes; // how to define array of 256 function pointers?
uint8_t op_nop();
uint8_t op_lxi();
uint8_t op_stax();
uint8_t op_mov();
uint8_t op_mvi();
Cpu();
void SingleStep();
};
Cpu::Cpu(): op_codes(new OpCode[256]{&Cpu::op_nop, &Cpu::op_lxi,
&Cpu::op_stax})
{
}
void Cpu::SingleStep()
{
uint8_t op_code = 0x00;
//call using std::invoke
std::invoke(op_codes[op_code], this);
//old style call without std::invoke
(this->*op_codes[op_code])();
}
```
GCC says:
```
<source>: In constructor 'Cpu::Cpu()':
<source>:18:79: internal compiler error: in gimplify_init_constructor, at
gimplify.cc:5780
18 | Cpu::Cpu(): op_codes(new OpCode[256]{&Cpu::op_nop, &Cpu::op_lxi,
&Cpu::op_stax})

All the other compilers accept this.
Even 4.9 ICEs for me though, so it looks like an old problem.
