stack-use-after-return错误是AddressSanitizer(一种内存错误检测工具)检测到的一种内存使用错误。这种错误发生在函数返回后,代码仍然尝试访问栈上的局部变量。由于函数返回后,栈帧通常会被销毁,这些局部变量所占用的内存区域可能会被其他数据覆盖或重新使用,从而导致未定义行为,如程序崩溃或数据损坏。 2. 分析导致stack-...

Use of stack memory after return in C In the following example, the integer_pointer_returning_function function returns a pointer to a stack variable, and there’s an attempt to access the memory of the returned pointer: int *integer_pointer_returning_function() { int value = 42; return &...
