[IronPython] HostCodeHeap leakage?

My guess is that's code in the JIT heap that's building up but I'm not 100% certain.  How is your code being executed?  Do you have the debug option (-D or -X:Debug) enabled?  To support debug mode we need to produce uncollectible code which could be building up.

Subject: [IronPython] HostCodeHeap leakage?

I am trying to find a memory/"performance" leak in an Ipy application.

Using WINDBG (!eeheap -loader), we noticed the that the LoaderHeap is getting bigger (150MB increase per day). From the !eeheap output it seems that the increase is due to HostCodeHeap (objects?).

As I understand these objects might be created by Ipy infra, is that right?

Is there anyway I can get more info on their content, or prevent them from growing?
