[mlpack] EXC_BAD_ACCESS in boost

[Li Dong]

Hi all,

I am using RangeSearch of MLPACK in my program, and it has no problem several days ago. But I made some changes to my codes these days, and encountered the following error in Debug mode:

iMac:Debug dongli$ lldb ./demo_testcase
Current executable set to './demo_testcase' (x86_64).
(lldb) r
Process 84476 launched: './demo_testcase' (x86_64)
Process 84476 stopped

In Release mode, there is no such error! My platform is Mac OS X 10.9.2, compiler is clang 5.1.0 in Xcode 5.1, boost version is 1.55.0.

Any idea? Thanks in advance!
