cygwin 에서 mpatrol 사용
cygwin 에 mpatrol-1.4.8 을 설치하였습니다.
manual 대로 test 를 돌려보려는데, 잘 안되는군요.
혹여 cygwin 에서 mpatrol 을 적용해 보신분 계시면 조언 부탁드립니다.
malloc 호출에 관한 test 인데, stackdump error 가 발생합니다.
gdb 로 따라가 보면, __mp_alloc 호출에서 recursion 이 발생하는 것
같습니다. 원인을 알 수 없고, 설치를 잘못한건지 모르겠습니다.
cygwin 에 설치는 auto-build tool(autoconf, automake etc..) 을
사용하여 build 하였습니다.

int main(void)
{
char* p;
p = (char*)malloc(10);
printf("0x%x\n", p);
return 0;
