Doing otherwise might cause your system to lockup for some time due to excessive paging. PS: Anyone who wants to try the second example should run the release build and should not run it in the debugger. Per thread data and it's more likely that thread creation will simply fail than to get R6016.īoth situations are possible in practice but it seems to me that you'd have to be quite unlucky for the outcome of memory corruption or lack of memory to be this R6016 error. The dll runtime relies on DLL_THREAD_ATTACH notifications to allocate the _flsindex isn't accessible if you're using the dll runtime so the first approach fails to link.
Note that in both cases the executable must be linked statically to the VC runtime. This one uses CreatedThread and exhausts all the heap memory before calling strtok - you get R6016 because the runtime cannot allocate memory for the per thread data. HANDLE hThread = CreateThread(nullptr, 0, ThreadProc, nullptr, 0, nullptr) #include įor (void *p (p = HeapAlloc(hHeap, 0, 50000)) != nullptr )įor (void *p (p = HeapAlloc(hHeap, 0, 50)) != nullptr ) This one simply "corrupts" the CRT's _flsindex variable, this will prevent the runtime from retrieving the per thread data even if the data was already allocated. Here are 2 ways to reproduce R6016: #include Įxtern "C" extern unsigned long _flsindex It has nothing to do with the stack either.
So, do you at least know what this error occurs? Does it happen during application startup or later? The typical reason for failure in this situation is lack of memory but that thread data structure is 100-200 bytes in size, I find it hard to believe that exactly this allocation fails, surely there are other allocations of roughly the same sizeĪnother reason could be failure of TlsSetValue caused by memory corruption but this seems unlikely too, you would have to be terrible unlucky to corrupt exactly the memory used by the TLS storage. To access some CRT functionality which requires a per thread data structure. To be precise, you won't get this error when the thread is created, you'll get this error later when you try This error can also happen when you create a thread by using CreateThread or any other function which doesn't use _beginthtread/_beginthreadex. I'm not sure how that can happen during at app startup, that would mean that the system itself is toast.Ģ.

This error can occur during app startup when the (non dll) C runtime is initialized. This seems to match your situation because you statically link the C runtime.īut this initialization occurs before your code gets a chance to run and the possible reasons for this include lack of memory and lack of TLS slots. That means you could take a look at it and get an idea about what's going on. The source of the C runtime is included with Visual Studio (check the VS installation folder\VC\crt\src). R6016 is a error generated by the VC runtime. Too bad that the error you are seeing has nothing to do with access violation or any other exception. Oh well, that sounds like the description of an access violation exception. So any type error that accesses a invalid memory error can be causing this problem."
"The error you are getting is caused by an access to a memory location outside the bounds that the operating system is allowing and causing an exception. "JDWeng, I agree with everything you just said"Įxcept that what he says has little to do with your problem. Is there some compiler setting somewhere that might influence this error? Or programming mistake?
Cardpresso error message windows#
I've only heard about this on Windows 8.1, but I wouldn't read too much into that. This happens very rarely (so I can't track it down), and it's been reported on more than one machine. Not sure if it's relevant, but I haven't overridden the default 1MB reserved stack size or heap size, and the total memory in use by my program is usually quite small (3MB-10MB on a system with 12GB actual RAM, over half of which is unallocated). One user reported this problem when the program was just However, my code only explicitly spawns a new thread in a couple of well-defined cases, neither of which are occurring here (although certainly the Microsoft libraries internally spawn threads at will). Microsoft documentation says this error message is generated when a new thread is spawned, but not enough memory can be allocated for it. My statically-linked Visual C++ 2012 program sporadically generates a CRTL error: "R6016 - Not enough space for thread data".
