Based on the provided crash report, the Terminal app crashed due to a **memory corruption error**.
The application's memory management system detected that a memory block had been corrupted while the app was attempting to save its persistent state, leading to a forced self-termination to prevent further data loss or instability.
EXC_CRASH (SIGABRT)
The app terminated itself with an "Abort trap: 6" signal. This is a common way for a program to stop itself when it encounters an unrecoverable internal error, such as a memory issue.
"libsystem_c.dylib":["abort() called"]
This explicit message confirms that the abort()
function was intentionally called from a system library, signifying a critical error.
The most telling evidence of memory corruption is found in the main thread's call stack. The sequence of function calls clearly indicates a failure in memory management.

nanov2_guard_corruption_detected
is the smoking gun. This function belongs to the memory allocation library (libsystem_malloc.dylib
) and its sole purpose is to detect when a memory block's metadata has been corrupted.malloc_zone_error
, which then triggers the abort()
function, causing the application to crash.Further up the call stack, we can see the context of the crash:

This part of the stack indicates that the crash happened during an operation to manage the application's persistent state. Specifically, the app was likely trying to append data (-[NSConcreteMutableData appendBytes:length:]
) related to an NSWindow
's state (-[NSWindow encodeRestorableStateWithCoder:]
) as part of a process to flush all changes by the persistent UI manager (-[NSPersistentUIManager flushAllChanges]
).
The Terminal app crashed because of a severe memory corruption error. This error was detected by the system's memory allocation library while the application was attempting to save its window state, forcing it to terminate to prevent potential data loss and further instability. The root cause is a bug in the app's code or a system framework that led to the corruption of a memory block's integrity.
