[Expectperl-discuss] Why two identical strings don't match using expect(-re)?

[Bruno N. <bn...@gm...>]

Hello all,

Can you tell me why isn't the expect(1, '-re', $string) bellow matching
successfully?

I put in color RED the debug message showing that the pattern in $string is
exactly what expect has on it's accumulator.

So why isn't it matching? There are some "\n" in the pattern, can it be a
problem?
