K-Bal, do you use option '-s' or '-Os' at compiling time ?
(I do.)

I don't know, I'll take a look this evening

I used -s but no -Os, however, those compiler settings don't make a difference.

Of course they don't. It only changes the executable file size, not the memory usage.

If you don't use -s your OS might load all debug symbols. Or I'm wrong ?

Anyway it seems not being the point here.

How are you getting the memory usage of the application? Linux and even Mac OS X for that matter don't always tell you the truth when it come to how much a program is actually using in memory. I've found that most of the time Linux will allocate a lot more memory than is needed for a program so the program can access more memory faster when needed.

You also have to take memory caches into account.

Yeah, might be. I just used the ubuntu system check tool.
