Description luz 2011-09-20 12:28:12 UTC 
version: 1.3.0-5605 (from http://www.libsdl.org/tmp/SDL-1.3.zip)

Error of Visual Studio Debugger:
Run-Time Check Failure #0 - The value of ESP was not properly saved across a function call.  This is usually a result of calling a function declared with one calling convention with a function pointer declared with a different calling convention.


example code:

void anyFunction
{
   unsigned long long k = 1;
   unsigned long long ksq = k * k ;
}

It seems that the function
void
__declspec(naked)
_allmul()

in SDL_stdlib.c destroy the stack.

Can you attach a full project that shows the problem?  I just tried to reproduce this and wasn't able to.

Thanks!

Colin Barrett fixed the _allmul issue in bug 1846.
