Control: severity -1 minor

sorry, I can't take bug reports with such exaggerations as serious.  Even more
if your issue looks like a local problem.

This really looks like a local problem. I've just checked and
gcc-9-base looks just fine here.

host:/tmp/foo$ dpkg -x /mirror/debian/pool/main/g/gcc-9/gcc-9-base_9.1.0-2_amd64.deb .
host:/tmp/foo$ 

Dan, check your system for other signs of problems please. Do you have
error messages from the kernel about storage or memory issues?
Something is corrupting those files at your end.

then it should quit out right away. Then the user will know he should
simply download it again.

For the deb attached below, dpkg proceeded much further, as shown in the
previous messages I posted in these reports, before finally quitting.
