Dear maintainer(s),

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

                        pass            fail
gcc-defaults           from testing    1.233
glaze                  from testing    7.9.1-1
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-defaults 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?
