c++11 threads - Operation not permitted exception

I'm writing c++11 multi-threaded application.

The main thread is reading from database and puts records in std::queue, threads are taking records from queue and process them.

Application is synchronised using std::mutex, std::condition_variable (defined as class members), methods are using std::unique_lock(class member mutex)

After some time (usually few minutes) - my application crashes with

terminate called after throwing an instance of 'std::system_error'
  what():  Operation not permitted

Program received signal SIGABRT, Aborted.
[Switching to Thread 0x7ffff5464700 (LWP 10242)]
0x00007ffff60b3515 in raise () from /lib64/libc.so.6

backtrace from gdb shows:

How can I get more information about this exception?

I am compiling and linking with -pthread option G++ 4.8.3 at Gentoo Linux machine -g option is enabled in both compiler and linker I tried disabling optimization
