| Subject: | IO::Scalar object causes script to die when you look at it in the debugger |
In the perl debugger, looking at a IO::Scalar object, as follows, dies.
$string = '';
$handle = IO::Scalar->new( \$string );
x $handle
DB<5> x $handle
0 IO::Scalar=GLOB(0x804c1b4)
-> *IO::Scalar::FH

This makes it extroidinarily difficult to debug, as you can't look at the object.
