problem with hexlify-buffer

problem with hexlify-buffer

[ian martins]

I'm using emacs-21.2.1 on win2k, compiled with nmake. (I tried some earlier 
versions also, and got the same result)

when I look at binary file with only an integer (32 bit) value of 60 or 
greater in it using emacs hexl-mode, it says:

00000000: 81a0 0000 00                             .....

it should say:

00000000: a00  0000                                .....

I've viewed the file with a different hex viewer and also xemacs and they 
both worked. for all values greater than 60 emacs sticks a hex "81" in front 
of the correct bytes.

in case it saves someone time, here is some c code that will create two 
files, one containing an integer value "59" (which emacs reads correctly) 
the other contains an integer 60 (which doesn't work for me)

#include <stdio.h>

void main()
{
  FILE *fout1, *fout2;
  int n1 = 159;
  int n2 = 160;
  int *p1 = &n1;
  int *p2 = &n2;

  fout1 = fopen("f159.good","wb");
  fwrite(p1, sizeof(int), 1, fout1);

  fout2 = fopen("f160.bad","wb");
  fwrite(p2, sizeof(int), 1, fout2);

  fclose(fout1);
  fclose(fout2);
}

please ask if I've left out needed info.

I find it curious because it doesn't show up on Emacs-21.2.1 on
GNU/Linux...

Are you sure you don't have an old hexl.el lurking somewhere along your 
load-path?  (Does "emacs -q -batch -f list-load-path-shadows" say something
about duplicate files?)  This problem used to happen in Emacs 20.x due to 
a bug, but that bug was fixed in Emacs 21, IIRC.

that command didn't say anything, but you are right. it was my fault.. I 
hadn't changed the load path in my .emacs file, so it was using the old 
stuff.

thank you so much, now I can return to the world that makes sense and emacs 
is infallible...
