Constructors of Global Variables Are Not Being Called

Any class that is instantiated in global space doesn't appear to call its constructor to initialise its member variables.


To reproduce:

* Start a new S32DS project

* Select MPC5777C (Not sure if this matters)

* Set language for all cores to C++

* Set the library for all cores to NewLib


Attached is the modifed main_z7_0.cpp that can reproduce the results. I am expecting both glob_val and local_val to be equal to 10 by the time the code gets to the for loop. But I am finding that glob_val is 0 and local_val is 10.


I am unable to use a pointer and initialise it in main.


Is there a configuration I am missing on the compiler/linker? Looking at the map file the crtbegin.o does not get linked in and I believe it has something to do with initialising this type of thing.
