因为startup-with-shell' is enabled, gdb has worked around this by caching a copy of your shell. The shell used by "run" is now: /Users/test/Library/Caches/gdb/bin/sh *warning: Mach error at "../../gdb/darwin-nat.c:273" in function "void darwin_nat_target::check_new_threads(inferior *)": (ipc/send) invalid destination port (0x10000003) ../../gdb/darwin-nat.c:1686: internal-error: void darwin_nat_target::init_thread_list(inferior *): Assertion !priv->threads.empty ()' failed.*
