Dear maintainer(s),

With a recent upload of gcc-defaults the autopkgtest of xsimd fails in 
testing when that autopkgtest is run with the binary packages of 
gcc-defaults from unstable on arm64 and armhf. It passes when run with 
only packages from testing. In tabular form:

                        pass            fail
gcc-defaults           from testing    1.233
xsimd                  from testing    14.3.0-1
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]. Of course, gcc-defaults shouldn't just break your 
autopkgtest (or even worse, your package), but it seems to me that the 
change in gcc-defaults was intended and your package needs to update to 
the new situation.

If this is a real problem in your package (and not only in your 
autopkgtest), the right binary package(s) from gcc-defaults should 
really add a versioned Breaks on the unfixed version of (one of your) 
package(s). Note: the Breaks is nice even if the issue is only in the 
autopkgtest as it helps the migration software to figure out the right 
versions to combine in the tests.
