"error: Duplicates declaration" when initializing struct in function with integer values

[fruffy]

Hello,
I have a question. After commit 259b2e4 I am hitting this error a lot:

when a structure is declared in a function and I use integer values to initialize. Is this an intentional restriction? It does not seem so.
Sample program attached.
