FYI, it looks like this new testcase requires

/* { dg-require-effective-target trampolines } */

as it is failing on a target without nested function support. 
Alternatively, maybe the testcase could be rewritten not to use a nested 
function?  I'm not sure if nested-ness is required to test the bug this 
issue was for.
