GNU gdb (GDB) Fedora (7.2-46.fc14)

The gcc version: actually, I noticed that maybe I should get a release 
version.
$ g++ -v

Tried different compiling options: "-g", or "-g -ggdb" or "-flto -O3 
<lots of options>". Since you asked, I double checked that linking step 
gets the above options.

What I get is:
Exception: Test
Backtrace:
./firstTest() [0x4036a8]
./firstTest() [0x40baa7]
./firstTest() [0x40e497]
./firstTest() [0x40807e]
./firstTest() [0x40851d]
/lib64/libc.so.6(__libc_start_main+0xfd) [0x3699c1ee5d]
./firstTest() [0x402d79]

With -O3 the only difference is the number of stack frames. "firstTest" 
is the name of the binary.
