我无法继续看到核心被倾倒。
我打字的时候得到了这个
gdb normal_estimation core
Reading symbols from /home/sai/Documents/pcl_learning/normal_estimation/build/normal_estimation...(no debugging symbols found)...done.
warning: core file may not match specified executable file.

Core was generated by `./normal_estimation'.
Program terminated with signal 11, Segmentation fault.
#0 0xb53101d6 in free () from /lib/i386-linux-gnu/libc.so.6
(gdb)
请让我知道我该怎么办?
