Ms.c crash with -RTCs

[gvanem]

Compiling the Packet_dll sources in debug-mode and with the switch -RTCs and using them in a simple program, I get a crash as show here:

Seems the definition of bool is to blame. Looking at the CPP output, I see

 typedef _Bool __crt_bool;
 ...
_Bool IsWow64()
{
       _Bool b = 0;

       if (Is64BitCode())
       {
              return 0;
      }
      if (IsWow64Process(GetCurrentProcess(), &b) == 0)
      {
              return 0;
      }

I had to build using WIN32COM_CPP with the latest WindowsKit. Bottom line seems to be, sizeof(bool) != sizeof(BOOL). I suggest you rewrite that since IsWow64Process() clearly should take a PBOOL.

-RTCs is Stack Frame runtime checking, a real handy switch in MSVC.

BTW, here is the stack backtrace:

enum_adapters!failwithmessage(void * retaddr = 0x012de50e, int crttype = 0n1, int errnum = 0n2, char * msg = 0x00b9f910 "Stack around the variable 'b' was corrupted.")+0x1ec
