static Rom g_Rom is not free

[spartazhc]

source/Lib/CommonLib/DepQuant.cpp:338 static Rom g_Rom;
There is no free for static Rom g_Rom, which will cause segment fault if I write an another encoderApp and encode some video multiple times.
I haven't read the context, but uninitiate it manually could fix it.
