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)

Hello,
A more current GDB is going to work better with GCC 3.0.3
(http://sources.redhat.com/gdb/current/). Can I sugges trying that and
then, if things still fail, fileing a bug report
(http://sources.redhat.com/gdb/bugs/).
