0x00002aaaab3b0b81 in opal_memory_ptmalloc2_int_malloc ()

from /opt/openmpi-1.3.4-gnu/lib/libopen-pal.so.0

At the point

Breakpoint 9, Index::Index (this=0x7fffffffcb80) at src/index.cpp:20

20 Name(0) {}

The Index has been called before this point and no problem:

-------------------------------------------------------

Breakpoint 9, Index::Index (this=0x117d800) at src/index.cpp:20

20 Name(0) {}

(gdb) c

Continuing.

Breakpoint 9, Index::Index (this=0x117d860) at src/index.cpp:20

20 Name(0) {}

(gdb) c

Continuing.

----------------------------------------------------------------------------

It seems that the 0x7fffffffcb80 address is a problem.

But, I donot know the reason and how to remove the bug.

Any help is really appreciated.

thanks

the following is the index definition.

---------------------------------------------------------

class Index {

public:

Index();

Index(const Index& rhs);

~Index();

Index& operator=(const Index& rhs);

vector<int> GetPosition() const;

vector<int> GetColumn() const;

vector<int> GetYear() const;

vector<string> GetName() const;

int GetPosition(const int idx) const;

int GetColumn(const int idx) const;

int GetYear(const int idx) const;

string GetName(const int idx) const;

int GetSize() const;

void Add(const int idx, const int col, const string& name);

void Add(const int idx, const int col, const int year, const string& name);

void Add(const int idx, const Step& col, const string& name);

void WriteFile(const char* fileinput) const;

private:

vector<int> Position;

vector<int> Column;

vector<int> Year;

vector<string> Name;

};

// Contructors and destructor for the Index class

Index::Index() :

Position(0),

Column(0),

Year(0),

Name(0) {}

Index::Index(const Index& rhs) :

Position(rhs.GetPosition()),

Column(rhs.GetColumn()),

Year(rhs.GetYear()),

Name(rhs.GetName()) {}

Index::~Index() {}

Index& Index::operator=(const Index& rhs) {

Position = rhs.GetPosition();

Column = rhs.GetColumn(),

Year = rhs.GetYear(),

Name = rhs.GetName();

return *this;

}
