Problem with --enable-c-cpplib and precompiled sources

["Andris Pavenis" <pavenis at lanet dot lv>]

Hi!

I tried to build egcs-1.1.1 release for DJGPP with configure option
--enable-c-cpplib. All things I have tested works except compiling already
precompiled source (see stack trace in attachment). This happens even with
empty file so contents doesn't mater.

>From  'gcc -c -v xxx.ii'   I'm getting SIGSEGV:

cpp_buffer *
cpp_push_buffer (pfile, buffer, length)
     cpp_reader *pfile;
     U_CHAR *buffer;
     long length;
{
  register cpp_buffer *buf = CPP_BUFFER (pfile);
			############    I'm getting buf==NULL here so SIGSEGV is
                 ############   natural
  if (buf == pfile->buffer_stack)
    {
      cpp_fatal (pfile, "%s: macro or `#include' recursion too deep",
       buf->fname);
      return NULL;
    }
  buf--;
  bzero ((char *) buf, sizeof (cpp_buffer));
