Hi Lucas,

thanks for your bug report.

Yesterday evening, 3 of us in the Perl team could not reproduce this
failure locally. From looking at the test and the actual code, what
seems to happen is that `traceroute' does not produce _any_ output,
which is a bit surprising.

Do you have any idea how this can happen in your test environment or
any information for us, what is special about it?


As a side note, the test itself is marked as TODO, i.e. expected to
fail, with a comment that it's fragile, so we might as well skip it
completely. - Oh, that comes from our own patch :) And the patch
headers mention #849933 and #980475.

Still, seeing the code explode _before_ reaching this stage is
puzzling.


Cheers,
gregor
