用上面的方法可以记录free的位置和参数，如果要记录malloc的位置，稍微复杂一点<br /> C/C++ code<br /> #include <stdio.h><br /> #include <stdlib.h></p> <p>void *<br /> debug_malloc(size_t size, const char *file, int line, const char *func)<br /> {<br /> void *p;</p> <p> p = malloc(size);<br /> printf("%s:%d:%s:malloc(%ld): p=0x%lx/n",<br /> file, line, func, size, (unsigned long)p);<br /> return p;<br /> }</p> <p>#define malloc(s) debug_malloc(s, __FILE__, __LINE__, __func__)<br /> #define free(p) do { /<br /> printf("%s:%d:%s:free(0x%lx)/n", __FILE__, __LINE__, /<br /> __func__, (unsigned long)p); /<br /> free(p); /<br /> } while (0)</p> <p>int<br /> main(int argc, char *argv[])<br /> {<br /> char *p;<br /> p = malloc(1024);<br /> free(p);<br /> return 0;<br /> }</p> <p>输出为：<br /> 052.c:28:main:malloc(1024): p=0x800902400<br /> 052.c:29:main:free(0x800902400)
