ubuntu 8.04 x64, codeblocks x64, gdb x64 = program x32... not x64

OK, this is something of an odd one as GCC on 64bit systems is supposed to default to 64bit programs so it's odd that it's defaulting to 32 bit in the first place (I'm assuming this has been altered on Ubuntu as far as my earlier comments are concerned). The only other thing I can think of is to try -mcmodel=medium but so far as I know the limit there is 2GB, not 4GB and it doesn't limit where pointers can point to (just where the program and its symbols can be).

Make absolutely sure of your version of gcc/g++ on the command line (gcc --version) or double check it in Synaptic. Other than that I think this might be better answered on the Ubuntu forums as it's getting more into compiller issues than a problem with C::B. Only thing that can confirm this is to try to compile the program on the command line rather than through C::B, trying the different -m... options, to see if something sticks that doesn't in C::B. If it does work better and the compiler selection in C::B is correct then there may be a bigger problem.

Its looks like its bigger problem...

after compiling in cmd line still same  problem :(

I'm not sure if that can cause your problem: do you have the appropriate kernel for your system, or is it a standard kernel that can not address the amount of memory you use ?
