[Santiago Vila]

Version: 1.8.0-3
Severity: important

Dear maintainer:

I tried to build this package in stretch with "dpkg-buildpackage -A"
but it failed:

I suspect of low entropy, but I'm not sure.

I'm using the "randomly" keyword here with the meaning "build-depends on
things which are not available as Debian packages and may or may not
be present on the autobuilder".

I've put several build logs here:
 
https://people.debian.org/~sanvila/build-logs/gpgme1.0/

[ BTW: If there is a particular reason why the build of this package
  allocated 165 GB of memory once or 229 GB another time, please
  tell me, I'm curious ].

Thanks.
