thread_local int g_cur_module_index = 0; thread_local MemoryModule g_memory_module[MAX_MEMORY_HOOK_RECURSIVE_DEEP] = {};

When I compile the program with Debug mode, the exception is not thrown. When I compile the program with Release mode, the exception is thown.

When I remove thread_local from g_cur_module_index and g_memory_module, the program runs OK in release mode。
