调用dlopen的库中入存在线程，则调用dlclose会出现segmentation fault

RT

若dlopen打开的库中不存在线程，或线程不在运行状态，则调用dlclose时，不会死机；
若存在运行时的线程，则dlclose时出现segmentation fault。
编译选项入下:
gcc -o main -lpthread -ldl main.c
gcc -g -rdynamic -shared -fPIC -o libtest.so test.c

求解！

用gdb调试吧。

gdb调试，堆栈如下： Program received signal SIGSEGV, Segmentation fault. [Switching to Thread -1219175536 (LWP 32698)] 0x0041a658 in ?? () (gdb) bt #0 0x0041a658 in ?? () #1 0x00000005 in ??

哥们解决没有？我遇到和你一样的问题，我用dlopen代开的库没有开启任何线程，但是dlclose的时候也会crash，很纠结
