从 macOS Catalina 开始，我开始收到无法重现的报告，但我知道它在哪里崩溃。寄存器rsi在内存中有以下选择器：
_controlStopTracking:at:inView:mouseIsUp:
SEGV_MAPERR 的地址0x000059b575cd55f8是由于0x000059b575cd55e0+0x18
AppKit where it crashes:
if (*(int8_t *)(var_90 + 0x18) != 0x0) {
[r14 _controlStopTracking:r15 at:sign_extend_64(*(int8_t *)(var_70 + 0x18)) inView:r8 mouseIsUp:r9];
}
报告来自多种系统/语言，我无法模拟崩溃。如何报告这个或我可以做更多的事情（调试）？
