Some spotting wanted

[Uwe Bonnes]

Hallo,

I am trying to track down some (for me ) strange problems. The installer
swcadiii.exe from www.linear-tech.com-> Software->Switchercad aborts,
reporting some problem with gunzip. I think this is caused by _fclose
reporting the EOF error. I instrumented dlls/msvcrt/file.c like

/*********************************************************************
 *		fclose (MSVCRT.@)
 */
int MSVCRT_fclose(MSVCRT_FILE* file)
{
  int r;
  r=_close(file->_file);
  TRACE("r 0x%08x flag 0x%08x %s\n",r, file->_flag, 
      (file->_flag & MSVCRT__IOERR)?"MSVCRT__IOERR":"");
  return ((r==MSVCRT_EOF) || (file->_flag & MSVCRT__IOERR) ? MSVCRT_EOF :0);
}

While the trace in line 321037 shows that MSVCRT__IOERR is not set, the
return value implies that MSVCRT__IOERR is set.

I run on a dual celeron. Is msvcrt perhaps not thread safe?

Bye
