MacOS 12 beta dyld error: file Array.h, line 54

Question

我编写了一个在 macOS Big Sur 上运行良好的 QT 应用程序。最近我升级到 MacOS 12 beta 2。编译过程仍然有效。但是应用程序无法启动。回溯堆栈显示它在 dyld 进程中崩溃。

dyld[16971]: Assertion failed: (idx < _usedCount), function operator[], file Array.h, line 54.

由于我在dyld期间无法停止并且没有dyld的源代码，所以我使用了一些标志来显示这个过程。然后我得到以下信息：

...
dyld[16806]: mprotect 0x000106D9C000->0x000106DA0000 to read-only
dyld[16806]: <libabsl_raw_hash_set.2103.0.1.dylib/bind#0> -> 0x7ff805b6d2b1 (libdyld.dylib/__tlv_bootstrap)

dyld[16806]: Assertion failed: (idx < _usedCount), function operator[], file Array.h, line 54.

我的问题是：1) 有什么方法可以调试dyld 并找出是哪个库导致了这个错误吗？ 2) dyld 日志是否表示错误在 libabsl_raw_hash_set 库中？ 3) 是否有可能它本身就是一个 dyld 错误并将在 MacOS Monterey 的发行版中得到修复？

非常感谢！

这已在 MacOS Monterey public beta 3 中修复。
