Hugh, forgot about comment#3.

Actually, running the above repro with --trace I get:

Stack overflow: IP: 0xb7d101fc, fault addr: 0xbf683ff8
At Unmanaged

Which I guess is the bug?

Anyway, running the normal StackOverflow repro (without the unmanaged function
scenario) I also get the bug.

With trace:

Stack overflow: IP: 0xb7df01fc, fault addr: 0xbf063ff8
At Unmanaged


Without trace: I get the correct exception but some debug information is
written in the console which I guess is not needed, right?:
