[Bug target/39738] GCC cannot build itself for win64 platform

["css20 at mail dot ru" <gcc-bugzilla@gcc.gnu.org>]

------- Comment #4 from css20 at mail dot ru  2009-04-12 08:50 -------
First tests of Win64 compiler.. simple source file test.c was created:

#include "windows.h"

int main(int argc, char **argv)
{
  MessageBox(NULL, "test", "test", MB_OK);
}

E:\temp\test>gcc test.c
gcc: CreateProcess: No such file or directory

E:\temp\test>gcc -### test.c
Using built-in specs.
Target: x86_64-pc-mingw32

 " \"" ------> <Here must be assembler path and arguments>

then compiler drivers segfaults.. gdb output:

Program received signal SIGSEGV, Segmentation fault.
main (argc=3, argv=0x72120) at ../../src/gcc/gcc.c:6848
6848    in ../../src/gcc/gcc.c


code from gcc.c(6848):
  /* Determine if there are any linker input files.  */
  num_linker_inputs = 0;
  for (i = 0; (int) i < n_infiles; i++)
    if (explicit_link_files[i] || outfiles[i] != NULL)
      num_linker_inputs++;


(gdb) p outfiles[i]
$12 = 0x72200 "test.c"
(gdb) p explicit_link_files[i]
No symbol "explicit_link_files" in current context - ???

disassembly listing:
000000000040DB7B  cmp         byte ptr [rbx+rcx],0   <--- rbx & rcx = 0
000000000040DB7F  jne         000000000040DB88 
000000000040DB81  cmp         qword ptr [rdi+rcx*8],0 
000000000040DB86  je          000000000040DB8B 

What is it, incorrect build or compiler driver bug ?
