Output must be "[thread number]: 0123456789" repeated for 10 threads for a
second.
The bug is easily discovered using: ./bug | sort | uniq
[140087293904640]: 0123456789
[140087302297344]: 0123456789
[140087310690048]: 0123456789
[140087319082752]: 0123456789
[140087327475456]: 0123456789
[140087335868160]: 0123456789
[140087344260864]: 0123456789
[140087352653568]: 0123456789
[140087361046272]: 0123456789
[140087369438976
[140087369438976]: 01234[140087369438976]: 0123456789
[140087369438976]: 0123456[140087369438976]: 0123456789
[140087369438976]: 0123456789
Clearly the output is bunch of mixed strings instead of many "[thread number]:
0123456789"
