PROCESSOR-SDK-J784S4: Cg7x compiler crash

Tool/software:

Hi,

I encountered a CGT 4.1.0 C++ compiler crash. I was able to reduce the source code so I may include it here 100

cg7x, cross compiling from Linux to C7X, ends with a "segmentation violation" with no other information. As the compilation is pretty long for a small source code, I guess the compiler goes in a deep recursion or something.c7x_segv.cpp

    Thank you for notifying us of this behavior, and for providing a concise test case.  I am able to reproduce the same behavior.  I filed the entry EXT_EP-11966 to have this investigated.  You are welcome to follow it with that link.

    Thanks and regards,
