I've observed that if Data struct defines a constructor, a compiler warning is thrown:

"warning #10210-D: creating ".esysmem" section with default size of 0x400; use the -heap option to change the default size".

It has no sense for me, it seems that compiler is inferring that heap is needed.

Regards.
