one thing that I noticed is that the old binary I released and
the new one built are behaving differently.

So whatever is the problem that you and me are seeing and that
Takashi's system seems immune is causing a difference at
compilation time in the executable:

Old binary:

octave:2> run test-round6a.m
octave:3> run test-round6b.m

New binary:

octave:1> run test-round6a.m
fatal: caught signal Segmentation fault -- stopping myself...
Segmentation fault (core dumped)

octave:1>  run test-round6b.m
fatal: caught signal Segmentation fault -- stopping myself...
Segmentation fault (core dumped)

Can you and Takashi provide me your cygcheck.out so that I can look on 
possible difference that could influence the build behaviour.

Of course I have W10 Home and Takashi a W10 Pro an that is already
a difference.

Regards
Marco
