Yeah, it occurred to me this morning that installing an octave-forge 
package might invoke the very compiler flags used to build Octave 
itself. So if debug was enabled for Octave, it'll apply to packages too.
Or is this a wrong supposition?
(BTW: This may be something for the wiki. This info may be obvious for 
the gurus, but is nowhere to be found.)

Now, I have done  "pkg install -forge windows"  from the debug octave 
build. So the backtrace I posted was from a "debug" windows package 
after all.

Hopefully I 'll have a chance to dig further somewhere the next days.

Philip
