gdb dumps core while setting breakpoint at main

[rajeev nair]

Hi,
Envirnoment: ia64 TurboLinux 2.4.1
             gcc version 2.9
             gdb version 5.0

I am facing a problem while debugging a C++ program
(which uses STL) with gdb. When i try to set
breakpoint at main, gdb dumps core.

Here is what i did..

elm2a114 src]$ gdb ./topo

topo is an exe which contains C++ files that uses
STL and are compiled with -ggdb.
Can anyone let me know what could be wrong..
Any help will be greatly appreciated.
Thanks
regards
rajeev
