We're also seeing a crash that looks like it might be related to:

https://code.google.com/p/go/source/detail?r=bb553699c7e6

Yesterday was a holiday, so I'll check again whether we're still seeing this later today.

My previous message:

We're seeing a crash that dvyukov suggested might be related to this CL.

runtime: unknown argument frame size for runtime.copy
fatal error: invalid stack

goroutine 0 [idle]:
runtime: unknown argument frame size for runtime.sigreturn
panic during panic

No stack trace beyond that.

I suspect it's happening in code with quite a deep stack that is using the copy builtin
on some memory mapped with syscall.Mmap.

Comment 1:

I can still reproduce this intermittently at tip. I'm happy to test any patches with
fixes or patches that add debug output to the runtime if that will help.
