          Issue ID: 22985
           Summary: dip1008 implementation uses the GC behind the scenes
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P1
         Component: druntime
          Assignee: nobody puremagic.com
          Reporter: razvan.nitu1305 gmail.com

int foo(int)  nogc
{
    throw new Exception("huhu");
}

void test()  nogc
{
    try
    {
        foo(1);
    }
    catch(Exception e)
    {
    }
}

void main()
{
    import std.stdio;
    import core.memory;
    auto stats1 = GC.stats();
    test();
    auto stats2 = GC.stats();
    writeln(stats1); // Stats(0, 0, 0)
    writeln(stats2); // Stats(1376, 1047200, 1360)
}

Allocating the traceHandler still uses the GC
