I don't understand: SYMIFY does translate hex addresses into human
readable file name and line number information.  addr2line does the
same, except that its UI is different.

Perhaps you meant why isn't the equivalent of SYMIFY part of the
standard library exit code?

If you want a version of SYMIFY that knows about debug formats other
than COFF (like stabs or DWARF2), like addr2line does, you can use
bfdsymify.exe from the GDB 5.1.1 distribution.  bfdsymify has the same
UI as SYMIFY.

If you want to use CMDLINE to get the name of the program, there's no
need for that: the crash message includes the full path to the
program's executable.  This is better than CMDLINE, since the latter
doesn't tell where to look for the .exe file.
