The following call sequence can cause an exception, when the locale is
not supported:
init_build_info -> scm_from_locale_string -> ... -> decoding_error
Then function scm_throw tries to access throw_var.
But this variable is not initialized yet, beacuse it is initialized in
scm_init_throw, which will be called later.
Therefore access to throw_var in init_build_info causes segmentation fault.
How to reproduce:
podman run --net=host -it fedora:36 \
/bin/sh -c 'dnf install -y gdb glibc-langpack-ru && export
LC_ALL=ru_RU.KOI8-R; exec gdb'
