I am getting compile time assertion failure on the following line of
code when I remove the optimization flag (-O3) in the Makefile. Is
this something expected ? I want to remove optimizations in order to
debug my code based on original source code line order not optimized
code order.

Yeah it's expected, but should be fixed. I just haven't looked into why the compiletime_assert() fails if optimizations are disabled. It really shouldn't, since the size of the struct is still 8 when disabled. So it's a bug in the compiletime_assert() code. Feel free to poke at it :-)
