Add error checking with Resume support and array bounds/dimensions and null-pointer checking, plus stack overflow checking with gas64 backend

Syntax

` -exx

`

Description

The -exx compiler option adds error checking with Resume support, array bounds and dimensions, and null-pointer checking (including the procedure pointers), plus stack overflow checking with gas64 backend.

Use of the -exx option automatically implies -e, -ex, -earray, -earraydims, -elocation, and -enullptr, error checking and code generation options.

Version

• Before fbc 1.20.0, array dimensions were never checked.
• Before fbc 1.10.0, stack overflow was never checked.
