This is related to bug 14440 which is because they are the same size (_Bool is the same
size as int on powerpc-apple-darwin).

Re-introduced by:
2004-06-07 Richard Henderson <rth@redhat.com>
* gimple-low.c (struct lower_data): Add the_return_label and
one_return_stmt.
(lower_function_body): Initialize and use them.
(lower_return_expr): New.
(lower_stmt): Call it.
* gimplify.c (gimplify_return_expr): Force the argument to be either
null or a result_decl.
* tree-gimple.c: Update gimple grammer to match.
* tree-ssa-copyrename.c (copy_rename_partition_coalesce): Deny
coalescing of result_decls.
The problem is that return statements no longer have stuff in them any more.

Here is the testcase I would add to the testsuite so this does not happen again:
/* { dg-do compile } */
/* { dg-options "-O2 -fdump-tree-tailc-details" } */
void *t();
char *f()
{
return t();
}
/* { dg-final { scan-tree-dump-times "Found tail call" 1 "tailc"} } */
