stack smash flags

[Keyur]

This is on v1.0.2:

I keep getting this compiler errors:
    libtest/main.cc: In function 'int main(int, char**)':
    libtest/main.cc:368: error: frame size too large for reliable stack checking
    libtest/main.cc:368: error: try reducing the number of local variables

I'm on Cent 6.2 (2.6.32-220.4.1.el6.x86_64) with GCC 4.4.6

The attached patch moves a bunch of variables in main.cc from the stack onto the heap and allows the compilation to go ahead.

The variables are not always freed especially so in the case of errors.

Making these into auto_ptr also takes up too much stack space and gives the same error.

I've made these flags optional via debug builds until we have a better understanding of which compilers are working with them.
