Re: [PATCH] gcc/testsuite/g++/bad-mapper-3.C: localhost might not be known

[Andre Vieira]

Hey Jonathan,

I think you are the right person to review this? If not do you who might be?

Kind regards,
Andre

The module-mapper uses Cody::OpenInet6 to open the connection to the
host. However, some distributions (such as Ubuntu 24.04) only have a v4
address for localhost:

   $ grep localhost /etc/hosts
   127.0.0.1  localhost
   ::1        ip6-localhost ip6-loopback

On these systems this test fails with "Name or service not known", so
add that to the list of allowed error messages.
