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，因此我使用了一些标志来显示该过程。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 并找出导致此错误的库？2) dyld 日志是否意味着错误在 libabsl_raw_hash_set 库中？3）它本身是否可能是一个dyld错误并且将在MacOS Monterey的发布版本中修复？
非常感谢！
