All reports of debian-source-options-has-custom-compression-settings for the archive. The extended description of this tag is:
The debian/source/options file for this package specifies a custom compression level or algorithm.
Whilst higher levels may reduce the size of big files, they have the side effect of consuming a lot of memory during both compression and extraction. This can not only also waste time unnecessarily, it can cause packages to FTBFS or even fail to install in resource-constrained environments or architectures.
Please remove the call and let dpkg-deb(1) select suitable defaults.
Refer to https://bugs.debian.org/829100 and the dpkg-deb(1) manual page for details.
