ahven 2.8-6 FTBFS causing other packages to wait for libahven11-dev

[Hans Joachim Desserud]

ahven 2.8-6 recently synced to Ubuntu Lunar [1] fails to build on amd64 and arm64 with core dumps:
x86_64-linux-gnu-gcc-12 perf_tester.o b__perf_tester.o /<<PKGBUILDDIR>>/obj-dynamic/obj/test/simple_listener.o /<<PKGBUILDDIR>>/obj-dynamic/obj/test/performance_tests.o -L/<<PKGBUILDDIR>>/obj-dynamic/stage/usr/lib/x86_64-linux-gnu/ -lahven -g -Wl,-Bsymbolic-functions -flto=auto -ffat-lto-objects -flto=auto -Wl,-z,relro -Wl,-z,now -Wl,--no-undefined -Wl,--no-copy-dt-needed-entries -Wl,--no-allow-shlib-undefined -L/<<PKGBUILDDIR>>/obj-dynamic/obj/test/ -L/<<PKGBUILDDIR>>/obj-dynamic/obj/test/ -L/<<PKGBUILDDIR>>/obj-dynamic/stage/usr/lib/x86_64-linux-gnu/ada/adalib/ahven/ -L/usr/lib/gcc/x86_64-linux-gnu/12/adalib/ -static-libgcc -lgnarl -lgnat -lrt -lpthread -ldl -Wl,-rpath-link,/usr/lib/gcc/x86_64-linux-gnu/12//adalib -o /<<PKGBUILDDIR>>/obj-dynamic//perf_tester

This in turn cause other packages to wait for libahven11-dev which is the new name of the dev package available in the latest version. (Mainly filed to keep track of the affected packages to see when the issue is resolved)

I tried reproducing the issue on Debian Sid without problems, so I don't know what's causing the core dump and if it is related to the gnat-transition.
