When I debug using GDB, an exception occurs during the invocation of cgocall(asmstdcallAddr, unsafe.Pointer(c)) : Segmentation fault; Line number: runtime/syscall_windows.go 544.

What did you expect to see?

normal running not Segmentation fault

This could mean that a seg fault occurs in the C code. Could you double check your C code?

Thanks.
