Wrapping CPP with static[int] generates wrong code

[dom96]

type
  SmallString* {.importcpp: "llvm::SmallString", header: "llvm/ADT/SmallString.h", noDecl.} [N: static[int]] = object

var x: SmallString[128]

Compiled with: nim cpp --passC:"-I/usr/local/opt/llvm/include" --passC:"-std=c++11" file

Error:

/private/tmp/aporia/nimcache/a4.cpp:24:27: error: template argument for non-type template parameter must be an expression
typedef llvm::SmallString<NI>  TY_7XJAavvgqEKfZ9bvblIL8mw;

Possible workaround:

type
  SmallString* {.importcpp: "llvm::SmallStringt<'0>", header: "llvm/ADT/SmallString.h", noDecl.} [N: static[int]] = object
