The first test checks for stack overflow. It uses a plural expression nested 5000 levels deep using the !(1-(...)) pattern. The parser accepts it (below YYMAXDEPTH=10000), but evaluation exeeds EVAL_MAXDEPTH=100 and falls back to index 0 instead of crashing with SIGSEGV. The second test checks for division by zero in plural expression. The expression (n!=1)+1/(n!=1729) triggers 1/0 for n=1729. msgfmt only validates 0<= n <= 1000, so the .mo file is accepted. Evaluation returns PE_INTDIV and falls back instead of raising SIGFPE. Adaptations from gettext to glibc: - gettext's plural-3 embeds the nested expresion as a literal string. This test uses an AWK script (plural-depth.awk) to generate the same expression. - gettext uses LANGUAGE= (empty) with LC_ALL=ll and its own locale setup. glibc requires a real locale for setlocale() or else the "C" locale override in dcigettext.c ignores LANGUAGE entirely. The tests are derived from GNU gettext's plural-3 (commit 021348871a22) and plural-4 (commit 429ba6c6b835), adapted to glibc's test framework.
