ISSUES

1. [New comment] Misleading error message with clr.AddReferenceToFileAndPath on a UNC path
http://ironpython.codeplex.com/workitem/31749
User jdhardy has commented on the issue:

"This is related to [workitem:31006] and [workitem:31383] as well."-----------------

2. [New issue] Memory Leak
http://ironpython.codeplex.com/workitem/31764
User MarkusSchaber has proposed the issue:

"IronPython seems to leak memory in some conditions.

The attached test case demonstrates the following cases:

- using Python.SetTrace(engine, delegate) leaks about 165k per script invocation.

- importing the warning module from the hosting environment leaks about 1.4 M per script run.

- importing the os module from the script also leaks about 1.4M per script.

- Doing both imorts also leaks about 1.4M per script(!).

- Combining all three of the above leads to an OutOfMemory Exception after about 331 cycles, boiling down to a leak of ~5MB per script run!

- Doing none of the above (only print) apparently creates a leak-free program.

I attached the test program. For the test runs above, I compiled it for .NET 4.0 and target "x86", as our production app also runs in that environment (.NET 4.0 and 32-bit only). Execution was on Win7 64 Bit. All windows updates installed."-----------------

3. [New comment] Memory Leak

User MarkusSchaber has commented on the issue:

"The program itsself (for easyer review)"-----------------

4. [New comment] sys.version is incomplete in user created engine, creating problems in platform.py
http://ironpython.codeplex.com/workitem/31736
User MarkusSchaber has commented on the issue:

"Does "Python.SetHostVariables(this ScriptEngine engine, string prefix, string executable, string version)" help?"
