Howdy

I have been looking through the archives and didn't have much luck with my
problem.

I have a couple of C programs I am trying to compile and run under cygwin.
The main() compiles into:

    0x41bd2c <main>: push   %ebp
    0x41bd2d <main+1>: mov    %esp,%ebp
    0x41bd2f <main+3>: sub    $0x630,%esp
    0x41bd35 <main+9>: push   %ebx
    0x41bd36 <main+10>: call   0x4f7430 <__main>
   ...

The __main() looks like:
    0x4f7430 <__main>: jmp    *0x11cb5e0
    0x4f7436 <__main+6>: nop
    0x4f7437 <__main+7>: nop

When run I ususally get:
  0x4f7430 in __main ()
  (gdb) stepi
  Cannot access memory at address 0x2000000. (A STATUS_ACCESS_VIOLATION
exception)


I can even get this behavior from the following program under DDD (but only
while single stepping machine instructions).
#include <stdio.h>

int     main()
{
        printf("Hello there.\n");

        return 0;
}

I tried to override __main() but it must be in the startup code since I was
not able to get my __main() to be used.

Thanks in advance.
