runtime: cannot run go.exe on Windows Server 2016

[huangyezuojia]

What version of Go are you using (go version)?

$ go 1.11

Does this issue reproduce with the latest release?

yes

What operating system and processor architecture are you using (go env)?

go env Output

$ go env
go  can not run

What did you do?

only run go.exe

What did you expect to see?

run success

What did you see instead?

D:\go\go1_11\go\src\runtime\sys_windows_amd64.s:60 is lasterror

more info:

cpu is intel xeon(R) silver 4110 cpu @ 2.10GHZ

[huangyezuojia]

maybe is cpu reason?

What precisely did you do? What precisely did you see?

[huangyezuojia]

What precisely did you do?

I just download the https://dl.google.com/go/go1.11.4.windows-amd64.zip, then run at window server 2016

the server's cpu is intel xeon(R) silver 4110 cpu @ 2.10GHZ

What precisely did you see?

similar to these url:

Exception 0xc0000005 0x8 0x0 0x0

my server is a remote server , i have not the right to copy output
but i remember the stack is below and some source code:

top0: Exception PC=0x0
top1: func (c *mcentral) grow()
top2: v, _, shouldhelpgc = c.nextFree(tinySpanClass)
top3: func mallocgc(size uintptr, typ *_type, needzero bool) unsafe.Pointer
top4: func newobject(typ *_type) unsafe.Pointer {

maybe the function have problem?

This function is suspicious
D:\go\go\src\runtime\mheap.go

func (h *mheap) alloc(npage uintptr, spanclass spanClass, large bool, needzero bool) *mspan {
// Don't do any operations that lock the heap on the G stack.
// It might trigger stack growth, and the stack growth code needs
// to be able to allocate heap.
var s *mspan
systemstack(func() {
s = h.alloc_m(npage, spanclass, large)
})

if s != nil {
if needzero && s.needzero != 0 {
memclrNoHeapPointers(unsafe.Pointer(s.base()), s.npages<<_PageShift)
}
s.needzero = 0
}
return s
}

another crash, need help

[ianlancetaylor]

Please tell us precisely what you did. List the exact commands that you ran. Don't just say "run at window server 2016". Tell us exactly what you did. Thanks.

decompress go1.11.4.windows-amd64.zip and run go.exe
i found some doubtful point

SUBQ $(maxargs*8), SP can align 16byte?

code at D:\go\go_1_11_5_src\go\src\runtime\sys_windows_amd64.s

// maxargs should be divisible by 2, as Windows stack
// must be kept 16-byte aligned on syscall entry.

i found the reason:

os_windows.go have not found a function _RtlGenRandom

code:

func loadOptionalSyscalls() {
	var kernel32dll = []byte("kernel32.dll\000")
	k32 := stdcall1(_LoadLibraryA, uintptr(unsafe.Pointer(&kernel32dll[0])))
	if k32 == 0 {
		throw("kernel32.dll not found")
	}
	_AddDllDirectory = windowsFindfunc(k32, []byte("AddDllDirectory\000"))
	_AddVectoredContinueHandler = windowsFindfunc(k32, []byte("AddVectoredContinueHandler\000"))
	_GetQueuedCompletionStatusEx = windowsFindfunc(k32, []byte("GetQueuedCompletionStatusEx\000"))
	_LoadLibraryExW = windowsFindfunc(k32, []byte("LoadLibraryExW\000"))

	var advapi32dll = []byte("advapi32.dll\000")
	a32 := stdcall1(_LoadLibraryA, uintptr(unsafe.Pointer(&advapi32dll[0])))
	if a32 == 0 {
		throw("advapi32.dll not found")
	}
	_RtlGenRandom = windowsFindfunc(a32, []byte("SystemFunction036\000"))
...
}

CL 536235 dropped RtlGenRandom in favor of ProcessPrng, so this failure mode is no longer possible.
