[Valgrind-users] Problems with XFree-4.3

[Olivier C. <oli...@fr...>]

Hello,

When I used valgrind (cvs head) with a programs which use the XFree-4.3.x
libraries I get the following:

[olivier@snoopy valgrind]$ valgrind -v xcalc
==21680== Memcheck, a.k.a. Valgrind, a memory error detector for x86-linux.
==21680== Copyright (C) 2002-2003, and GNU GPL'd, by Julian Seward.
==21680== Using valgrind-1.9.4, a program supervision framework for x86-linux.

==21680==
==21680== Valgrind detected that your program requires
==21680== the following unimplemented functionality:
==21680==    x86 segment override (SEG=CS) prefix
==21680== This may be because the functionality is hard to implement,
==21680== or because no reasonable program would behave this way,
==21680== or because nobody has yet needed it.  In any case, let me know
==21680== (js...@ac...) and/or try to work around the problem, if you can.
==21680==
==21680== Valgrind has to exit now.  Sorry.  Bye!

If I use the XFree-4.2.1 libs I've not this problem.

Any help welcome ...

Thanks a lot for valgrind, a great software!
