In debug builds, this test fails with `SIGABRT` due to an assertion. In release builds, truncation of the fractional part will be detected. Sometimes, this test may also cause memory violation (`SIGSEGV`) due to it being undefined behavior to set locale and use locale-dependent functions concurrently. On Windows, this does not happen since the global locale is protected by a mutex. This test assumes that a locale called "de_DE.UTF-8" exists on the host. If it does not, the test bails out but does not fail. The locale name is hard-coded because it is impossible to query available locales portably. "de_DE.UTF-8" is an accepted format on Ubuntu, macOS, and Windows. Signed-off-by: Jonas Greitemann <jgreitemann@gmail.com>
