c++: internal compiler error: Killed

原因：内存不足，SWAP不足

1. 创建分区文件，大小 4G

    [root@dbmspreapp205 ~]# dd if=/dev/zero of=/data/swapfile bs=1k count=4096000
    4096000+0 records in
    4096000+0 records out
    4194304000 bytes (4.2 GB) copied, 11.5204 s, 364 MB/s
   

2. 生成 swap 文件系统

    [root@dbmspreapp205 ~]# mkswap /data/swapfile
    mkswap: /data/swapfile: warning: don't erase bootbits sectors
            on whole disk. Use -f to force.
    Setting up swapspace version 1, size = 4095996 KiB
    no label, UUID=579f326b-b767-45e9-88f6-88348eea5414
   
    [root@dbmspreapp205 ~]# mkswap -f /data/swapfile
    Setting up swapspace version 1, size = 4095996 KiB
    no label, UUID=0b1356c5-b1e2-40c6-9142-627a7e38e2ca
   

3. 挂载 swap 文件

    [root@dbmspreapp205 ~]# swapon /data/swapfile
    [root@dbmspreapp205 ~]# free -m
                 total       used       free     shared    buffers     cached
    Mem:         15948      15746        202          0        378       8830
    -/+ buffers/cache:       6537       9411
    Swap:        14239         70      14169
   

4. 卸载 swap 文件

    [root@dbmspreapp205 ~]# swapoff /data/swapfile
    [root@dbmspreapp205 ~]# free -m
                 total       used       free     shared    buffers     cached
    Mem:         15948      15744        204          0        378       8830
    -/+ buffers/cache:       6535       9413
    Swap:        10239         70      10169
   

5. 修改 /etc/fstab 文件，新增如下内容：

    /data/swapfile swap swap defaults 0 0
