Error: cannot allocate vector of size 64.0 Mb

rt，怎么不能无法分配大小为64mb的连续内存空间，这个太唬人了吧

nan.xiao

可能是没有连续的地址空间了

Error messages beginning cannot allocate vector of size indicate a failure to obtain memory, either because the size exceeded the address-space limit for a process or, more likely, because the system was unable to provide the memory. Note that on a 32-bit build there may well be enough free memory available, but not a large enough contiguous block of address space into which to map it.
