i only keep one copy of libcurl libray, so i am sure both my program the the test program
will load the same library in run-time.

just now i use gdb to debug my program and the test. Both of them run the same except
after the connect() function is called. My program returns errno = 22(Invalid argument)
and the test return errno is 150(which is correct in debuging i think). Why??

Below is part of the compared info between them(i have saved the total debug information,
if anyone think the following is not enough, i will present more later)
