My first advise:
Don't copy through stack such big structure use references and pointers.

Second advise:
If your project is automake based then open Project -> Project Settings -> 
Configure settings. Select your build configuration and on C tab in field 
"Compiler settings (CFLAGS)" and on C++ tab in field "Compiler settings 
(CXXFLAGS)" enter -mmax-stack-frame=10000000

For custom makefile based project use CFLAGS and CXXFLAGS variable in your makefile.
