I separately filed the true std.json regression as issue 11527.
After fixing the bug, the OP case will print following errors.

C:\dmd2\src\phobos\std\json.d(181): Error: Unions with overlapping fields are
not yet supported in CTFE
C:\dmd2\src\phobos\std\json.d(103):        called from here: this.assign(v)
test.d(6):        called from here: v.integer(1L)
test.d(12):        called from here: foo()

The error is caused by issue 11510, and could be fixed by my compiler
enhancement fix.

I change this to dmd issue.
