g++ & gdb core dumped !! Please help !!

[Krishna Murthy Gudipati]

Hello Friends,

 

I HAVE DOWNLOADED 'binutils' & 'gcc-3.0.3' BINARIES FOR SOLARIS 7 AND
SUCCESSFULLY INSTALLED THEM. TO TEST THE COMPILER I HAVE WRITTEN A SMALL PROGRAM :

 

********----------------------------Begin--------------------------------------

 

#include <iostream.h>

 

int main (){

 

cout << " This is test program" << endl;
return 0;

 

}

 

********------------------------------End--------------------------------------

 

WHEN COMPILED IT IS 'OK' (compiled) BUT WHEN I RUN THE PROGRAM IT CORE DUMPED :

 

********---------------------------Begin---------------------------------------

 

student4%>g++ -o testrun test.cpp
student4%>./ testrun
Segmentation Fault (core dumped)

 

********----------------------------End----------------------------------------

 

THEN I HAVE DOWNLOADED 'gdb' AND INSTALLED SUCCESSFULLY. AND WHEN TRIED TO TRACE
THE PROGRAM EVEN 'gdb' ALSO CORE DUMPED WHILE USING COMMANDS 'bt', 'where' :

 

********---------------------------Begin---------------------------------------

 

student4%> g++ -o testrun -g t.cpp
student4%> testrun
Segmentation Fault (core dumped)
student4%> gdb testrun core

SOLVE IT. PLEASE SUGGEST ME IN THIS REGARD.
