I have always been a little confused about the
affect that the LINK /DSF qualifier has on traceback. Specifically, is it not possible to still get module, routine, and line number information in a %TRACE-F-TRACEBACK display if /DSF is used?
Here is an example. Just for fun, I mix languages.
------------------------------- foo.for --------------------------------
PROGRAM FOO
* This isn't a quote it is an apostrophe.
INTEGER BAR
CALL CRASHME
END
------------------------------- foo.for --------------------------------
----------------------------- crashme.cxx ------------------------------
// $Workfile$
//
// $Log$
#ifdef __VMS
#pragma module CRASHME
#endif
extern "C" void CRASHME() {
throw *(int*)0;
}
----------------------------- crashme.cxx ------------------------------
$ fortran/version
HP Fortran V7.6-4120-48DA2
$ cxx/version
Compaq C++ V6.5-021 for OpenVMS Alpha V7.3-1
$ fortran foo/debug=all/noopt
$ cxx crashme/debug=all/noopt
$ cxxlink/traceback foo,crashme
$ run foo
%SYSTEM-F-ACCVIO, access violation, reason mask=00, virtual address=000000000000
0000, PC=0000000000030084, PS=0000001B
%TRACE-F-TRACEBACK, symbolic stack dump follows
image module routine line rel PC abs PC
foo CRASHME CRASHME 10 0000000000000014 0000000000030084
foo FOO FOO 4 0000000000000044 0000000000030044
foo 0 00000000000238EC 00000000000338EC
0 FFFFFFFF802874D4 FFFFFFFF802874D4
$ cxxlink/traceback/dsf foo,crashme
$ run foo
%SYSTEM-F-ACCVIO, access violation, reason mask=00, virtual address=000000000000
0000, PC=0000000000030084, PS=0000001B
%TRACE-F-TRACEBACK, symbolic stack dump follows
image module routine line rel PC abs PC
foo 0 0000000000020084 0000000000030084
foo 0 0000000000020044 0000000000030044
foo 0 00000000000238EC 00000000000338EC
0 FFFFFFFF802874D4 FFFFFFFF802874D4
Personally, I think the /DSF qualifier is a great idea, but not if I loose traceback information in production.
