If you want to modify function-local variables via some form of stack inspection/modification in an attempt to add global exception handling in C I'd respectfully suggest you are doing it wrong.
C based interpreted languages have these kinds of features without breaking C. Maybe you don't really want C at all.
Also gdb has all these introspection capabilities. Learn the debugger.

DL(3) Library Functions Manual DL(3)
NAME
DL - generate logging messages in C and C++ using a debugger
SYNOPSIS
#include <DL.h>
DL(format,...)
DLG(guard,format,...)
DLH(handler,format,...)
DLP(param,format,...)
DLGH(guard,handler,format,...)
DLHP(handler,param,format,...)
DLGHP(guard,handler,param,format,...)
DESCRIPTION
The DL macro is used to print logging or debugging messages using a debugger. The nana(1) command generates a set of debugger commands
which are then sourced into gdb(1) to implement the logging. If you don't run the executable under gdb(1) then no tracing will occur. The
arguments are:
format,... - a printf(3) style argument list containing the message
guard - print only if the guard is true.
handler - the code that does the printing. Default: fprintf
param - a parameter to be passed off to the handler. Default: stdout
See nana.info for details on configuring the behaviour.
SEE ALSO
nana-clg(1), nana(1), nana(3), I(3), DI(3), L(3), DL(3), Q(3) and nana.info.
The nana.info file is the primary documentation for this library.
