The function char_table_translate may allocate some amount
of memory.  But that's only when the char-table is one of a
"unicode character property table" loaded via the function
uniprop_table.  When char_table_translate is called from
re_search_2 (via the macro RE_TRANSLATE), the char-table to
lookup is one of a case-related table (equiv? canon?) which
is not a unicode property table.

The function that acutally allocates memory via.
char_table_translate is uniprop_table_uncompress.
