if(defined(undef)) gives can't use undefined value as a SCALAR reference.

[Dave Horner]

Hello all,

I am trying to understand the strangeness encountered when trying to use
HTTP 1.1 100 continue status. not by choice mind you; I am not sure why I
am getting the 100 continue response, which is requiring the expect
100-continue header, otherwise a timeout results.

Bug #97772 for Artifactory-Client: zero length file uploads
https://rt.cpan.org/Public/Bug/Display.html?id=97772

'expect' => '100-continue' undefined value as a SCALAR reference #63
https://github.com/libwww-perl/libwww-perl/issues/63

if(defined($wbits)) is giving me can't use and undefined value as a SCALAR
reference.

Could someone please enlighten me on how such a thing is possible? I
thought that was the point of defined to test for undef. this is a bizarre
result.

Thanks everyone,
