From: Kirill Batuzov <batuz...@ispras.ru> Clocks are initialized in qemu_init_main_loop. They are not needed before it. Initializing them twice is not only unnecessary but is harmful: it results in memory leak and potentially can lead to a situation where different parts of QEMU use different sets of timers.
To avoid it remove init_clocks call from main and add an assertion to qemu_clock_init that corresponding clock has not been initialized yet.
