When I try to build gobject-introspection, I get this crash in the gir 
directory.  I am building gobject-introspection from git master on Solaris x86.

  CC    /tmp/tmp-introspectgQAquA/Everything-1.0
  make[2]: *** [GIRepository-2.0.typelib] Segmentation Fault (core dumped)

I notice that this crash is from tools/g-ir-compiler.  When I run gi-ir-
compiler in dbx, I see the crash is happening here.

Here is line 1249 of girnode.c where the crash seems to be happening:

 1247     if (node->tag < GI_TYPE_TAG_ARRAY)
 1248       {
 1249         g_string_append_printf (str, "%s%s", basic[node->tag],
 1250   			      node->is_pointer ? "*" : "");

The reason for the crash is that node->tag is 23, but basic[23] is 
uninitialized.  basic[22] is the highest value that is initialized.

Looking at girepository.h at the GiTypeTag structure, I notice that GI_TYPE_TAG_ARRAY is 24.   However the basic array in the serialize_type function in girnode.c only has 22 elements.  I suspect this is the reason?

Should not the basic array in serialize_type in girnode.c match up with the GiTypeTag in girepository.h?

Note sure how to fix this, but wanted to highlight the issue.
