Users don't expect a new reference returned from a get() function.
Indeed, all users of that API I foud where NOT destroying the reference.
Just change the implementations to NOT return a reference.
This applies to the following APIs:
hb_unicode_funcs_get_default()
hb_glib_get_unicode_funcs()
hb_icu_get_unicode_funcs()
Fixes https://github.com/harfbuzz/harfbuzz/issues/1134
return;
hb_unicode_funcs_destroy (unicode);
- unicode = hb_unicode_funcs_get_default ();
+ unicode = hb_unicode_funcs_reference (hb_unicode_funcs_get_default ());
flags = HB_BUFFER_FLAG_DEFAULT;
replacement = HB_BUFFER_REPLACEMENT_CODEPOINT_DEFAULT;
if (!unicode_funcs)
unicode_funcs = hb_unicode_funcs_get_default ();
-
hb_unicode_funcs_reference (unicode_funcs);
hb_unicode_funcs_destroy (buffer->unicode);
buffer->unicode = unicode_funcs;
