source code
I think this is a bug. The code sounds sound and it works normally if I compile
with GCC.
The source code is attached. The file `in` is above. Ex:
$ gcc -ggdb -pthread thread.c
$ ./a.out < in
1 2 3
4 5 6
7 8
9 10
11 12
BEFORE SLEEP
AFTER SLEEP
AFTER JOIN
58 64
139 154
Count: 4
$ clang -ggdb -pthread thread.c
$ ./a.out < in
1 2 3
4 5 6
7 8
9 10
11 12
BEFORE SLEEP
AFTER SLEEP
Segmentation fault (core dumped)

I suppose this is an bug in clang.
