See if this fixes your problem. I am not certain I didn't miss something. But if that
works, we will ask others to review it.

See my reply on https://golang.org/cl/7563043. If someone can make it work, it should be cheap enough to do always. |
Russ, Here is CL https://golang.org/cl/11266043/ that changes both usleep and osyield to run on os stack. But it is crashing in misc/cgo/test during cgo callback, because m is not set (see below). It is crashing in usleep, not osyield, but I think it just matter of luck. So I think we cannot assume m is set, therefore we cannot switch stacks here.

This issue was closed by revision 45cff65. Status changed to Fixed. |
my repro case now seems to pass without problems (thanks!), but the stdlib test suite
still barfs, eg.
$ GOOS=windows go test unicode/utf16
fatal error: malloc/free - deadlock

hanwenn, Your stack dump is not very useful. I have seen "stack unavailable" message before https://golang.org/issue/5873. Please try and see if you can get better stack trace somehow. Perhaps use gdb to discover where it fails. Thank you. Alex Status changed to Accepted. |
Once issue #5873 is fixed maybe we can get more information about Han-Wen's current problem. |

Hi there, I'm seeing something that looks like a race condition. Symptoms: * on Linux, run GOOS=windows go run standalone.go => ... fatal error: malloc/free - deadlock [signal 0xc0000005 code=0x0 addr=0x30 pc=0x41f570] goroutine 1 [chan receive]: net/rpc.(*Client).Call(0x8de7300, 0x686860, 0x3, 0x5bf0a0, 0x8de0508, ...) /home/hanwen/vc/go/src/pkg/net/rpc/client.go:310 +0xa9 main.main() /home/hanwen/go/src/barf/standalone.go:47 +0x312 * This is on Ubuntu 12.04 on amd64, with the .exe running on Wine 1.4-0ubuntu4.1. * When applying works.patch, it goes back to working. I've also bisected this problem to https://code.google.com/p/go/source/detail?r=f800157ce425 * It's possible that this a Wine problem, but anecdotally, we've seen frequent runtime crashes on Windows 7 on VMWare with the original program too (dialog box with "your program has stopped."). * If this is a Wine problem, what kind of bugreport should I file with the Wine folks? * I'm on parent: 17191:a1fe2e3fadb0 tip misc/vim: Add compiler plugin for Go branch: default commit: 3 modified, 5 unknown update: (current)Attachments:
