GDB回溯在Mac上不顯示函數名稱

Question

我正在使用此代碼使用gdb測試某些東西（這是錯誤的代碼，我僅將其用於測試目的）：

#import <Foundation/Foundation.h>

int main (int argc, char **argv)
{
    NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];

    int i = 1;  

    NSLog(@"Hi GDB, i is %@", i);

    [pool release];
    return 0;
}

然后我編譯它： gcc -Wall -g -framework Foundation testGdb.m -o testGdb ，然后運行它：

gdb ./a.out

#1  0x0000000000000000 in ?? ()

（gdb）

奇怪的是，在（＃1）中沒有名字，正確的輸出通常會打印NSLog（導致崩潰的原因）和main。

感謝您幫助理解這種奇怪的行為。

Answer 1

這個答案很可能也適用於此。

調試符號與問題無關-GDB不用它們就可以展開堆棧（僅需要展開描述符）。
