The following made up LC_MONETARY section causes localedef to die with a
SIGSEGV:
$ cat foo.src && ./localedef -w -c -f
/nfs/devco/sebor/stdcxx/etc/nls/charmaps/ISO-8859-1 -i foo.src foo || gdb -q
./localedef
LC_MONETARY

currency_symbol "klmn"
mon_decimal_point "@"
mon_thousands_sep "|"
mon_grouping 5
positive_sign "<"
negative_sign ">"
int_frac_digits 6
frac_digits 7
p_cs_precedes 1
p_sep_by_space 1
n_cs_precedes 1
