Hi Roderich,
Thanks for your good explanation. It is really appreciated.
When I packed my perl files, I discover the program didn't work as
expected and
I had to dig down for not few days in order to discover $0 was not working
properly.
As you have shown, you have gone one step further, it seems the issue is
related with
the shrink of the environment but I think this is something quite weird.
The issue I see here is that there is a command (not PAR'ed ) that is
working properly,
and then, when it is PAR'ed, it has different behaviour, which this is
something I see not acceptable.
I remember perlcc could change the behaviour of the program because it does not
guarantee full
compliant, but I didn't read anything about it in PAR. Indeed, I think I see
some references saying
use PAR if you do not want to see a weird behaviour in your program.
PAR should not shrink the environment variable in a way the behaviour of
the program
is changed (!!). If it does that (I'm pretty sure there could be a good reason
for it, but I am not
an expert) it should not affect the specification of the program, as it seems
it does.
My point heres are 2 then:
Could this be fixed?
If not, could it be a workaround in which this "shrinking" environment in the
PAR files could be overcome and the behaviour of the programs are not changed?
Thanks
Miguel.
