[Debian-astro-maintainers] Bug#960212: gcc-9 breaks iraf autopkgtest: gcc: not found

[Paul Gevers]

Source: gcc-9, iraf
Control: found -1 gcc-9/9.3.0-12

Dear maintainer(s),

With a recent upload of gcc-9 the autopkgtest of iraf fails in testing
when that autopkgtest is run with the binary packages of gcc-9 from
unstable. It passes when run with only packages from testing. In tabular
form:

                       pass            fail
gcc-9                  from testing    9.3.0-12
iraf                   from testing    2.16.1+2018.11.01-3
all others             from testing    from testing

I copied some of the output at the bottom of this report.

Currently this regression is blocking the migration of gcc-9 to testing
[1]. Due to the nature of this issue, I filed this bug report against
both packages. Can you please investigate the situation and reassign the
bug to the right package?
