This simple script triggers an assert during compilation of the script:

class TestClass
{
  TestClass(array<int> arr)
  {
    this.arr = arr;
  }

  private array<int> arr;
}

void main()
{
  TestClass @t = TestClass({});
}

The assert triggered when main is called is:

as_compiler.cpp:6474: asUINT asCCompiler::ImplicitConversion(asCExprContext *, const asCDataType &, asCScriptNode *, EImplicitConv, bool, bool):
Assertion `ctx->type.dataType.GetTokenType() != ttUnrecognizedToken || ctx->type.dataType.IsNullHandle() || ctx->IsAnonymousInitList()' failed.

The call stack shows that asCCompiler::ImplicitConversion is called from asCCompiler::CompileConstructCall at as_compiler.cpp:10935, and it's only called when the constructor has exactly one argument. Working around the issue by adding another argument to the constructor works just fine.

I've fixed this in revision 2588.

Thanks! That does indeed fix the issue for me.
