Description Behdad Esfahbod 2013-09-06 20:56:04 UTC 
I have this:

typedef const struct hb_language_impl_t *hb_language_t;

The aim is for hb_language_t to be used a pass-by-value type.  However, g-i doesn't recognize this and generates these kinds of warnings:

/home/behdad/src/freedesktop/harfbuzz/src/hb-common.h:138: Warning: HarfBuzz: hb_language_from_string: return value: Invalid non-constant return of bare structure or union; register as boxed type or (skip)

I can register it as boxed, but that would result in unnecessary copies all over.
Comment 1 Behdad Esfahbod 2013-09-06 20:56:33 UTC 
In general, I expect that typedefs to pointer types will just be expanded and behave as if the typedef was not there.

Comment 3 Behdad Esfahbod 2015-05-20 00:42:21 UTC 
Has this happened or otherwise changed in recent versions?  I just upgrade to Ubuntu 14.04 and this works as I would expect...
