I have a function that allocates a closure somewhere in it (as

I can't make the function nogc as it calls a lot of other GC

profilegc.log only gives me the line number of the function
signature, which doesn't give me any hint as to where in the
function the closure is allocated.
Anyone have any nice tricks to help narrow this down.
This hack seems to show the detailed info of @nogc also in normal
code.
