unpredictable crash

Hi

I am using the xlC_r compiler on AIX 5.2 - this program crashes with a
segmentation fault (core dumped) - I compile with a command: xlC_r
filename.C - no switches or anything
------------------------------------------------------------------------------------------------------------------------
#include <iostream.h>
#include <string.h>

char* myfunc()
{
    char *temp;
    temp = new char(100);
    strcpy(temp, "Hello world man");
    return temp;
}

int main()
{
    cout << myfunc() << endl;
    return 0;
}
---------------------------------------------------------------------------------------------------------
#include <iostream.h>
#include <string.h>

char* myfunc()
{
    char *temp;
    temp = new char(100);
    strcpy(temp, "Hello world man");
    return temp;
}

int main()
{
    cout << myfunc() << endl;
    return 0;
}
----------------------------------------------------------------------------------------
but this does'nt:

#include <iostream.h>
#include <string.h>

char* myfunc()
{
    char *temp;
    temp = new char(100);
    cerr << "1" << endl;
    strcpy(temp, "Hello world man");
    return temp;
}

int main()
{
    cout << myfunc() << endl;
    return 0;
}
_----------------------_----------------------_----------------------_----------------------_----------------------

The only change is the

cerr << "1" << endl;

line

Any idea why this happens? And also, how do you read a core dump? Any
tools, information regarding this? I opened the core file in a hex
editor and there was too much information to make any sense

Thanks
