Justification: Fails to build from source but built in the past.
glibc 2.34 FTBFS on Alpha with a segfault occuring during building
locales. From the build log:
Generating locale en_US.UTF-8: this might take a while...

In the build directory I reran ./debian/rule build-arch to get a
coredump. Debugging reports:
