Bug#987637: fenix FTBFS with gcc 10

[Baptiste Beauplat]

Control: tags -1 + patch

Dear maintainer,

The following patch fixes the FTBFS. I've added a specific check in the
test suite and I've tested it manually.

Without feedback, I'll NMU the package and request an unblock in a
couple of days.

Best,
