runtime: leftover defers

[bradfitz]

The linux-amd64-clang builder has been complaining about leftover defers.

I have no clue why it's only the clang builder, but there are three of them recently.

runtime: g1832: leftover defer sp=0xdeaddeaddeaddead pc=0x405a9c
    defer 0xc2086a45f0 sp=0xdeaddeaddeaddead pc=0x405a9c
    defer 0xc2086c2060 sp=0xdeaddeaddeaddead pc=0x40500e
fatal error: traceback has leftover defers

In:

I also see these on the Windows builders.

I cannot reproduce it here. But I didn't tried hard enough.

I just had this error as well: https://gist.github.com/mattyw/31e701977f213ac07279
I've taken off parts of the traceback to hide some proprietary stuff - if you need more let me know and I'll see what I can do.

go version devel +1757b5c Thu Dec 11 07:31:32 2014 +0000 linux/amd64

The process had been running for >3 days when this occurred

I haven't seen one of these in a while. Please reopen if you're still seeing it.
