cygwin 上的内存泄漏工具

内存泄漏工具在cygwin上的使用

$ apt-cyg install valgrind

c
#include 
#include 
void foo() {
    int* ptr = malloc(sizeof(int));
    *ptr = 10;
    printf("Value: %d\n", *ptr);
}
int main() {
    foo();
    return 0;
}

$ valgrind ./leak

==1234== 4 bytes in 1 blocks are definitely lost in loss record 1 of 1
==1234==    at 0x4C2DB8F: malloc (in /usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so)
==1234==    by 0x40052F: foo (leak.c:6)
==1234==    by 0x40054F: main (leak.c:12)

c
void foo() {
    int* ptr = malloc(sizeof(int));
    *ptr = 10;
    printf("Value: %d\n", *ptr);
    free(ptr);  // 修复内存泄漏问题
}
