Could you gdb the core and print some outputs:

fr 5 (or whichever frame number has client_check_command_hangs)
p *client
p *client->command_queue
p *client->command_queue->next
p *client->command_queue->next->next
(etc, until it fails)
p *current_ioloop
p *current_ioloop->io_files
p *current_ioloop->io_files->next
p *current_ioloop->io_files->next->next
(etc, until it fails)
