[Valgrind-users] Impossible error: VG_(mash_LD_PRELOAD_and_LD_LIBRARY_PATH): inter nal error:

[Ing, G. <gi...@so...>]

Here's an email I just sent to jseward, in case anyone else on this list has
ideas or experience with this. Thanks!

I received one of your "impossible errors". Have you found a cure for these
yet?

gcc version 3.2 20020903 (Red Hat Linux 8.0 3.2-7)
Red Hat Linux release 8.0 (Psyche)
glib-1.2.10-8
valgrind-20030725

As per your FAQ, nothing in my executable modifies (or even reads)
environment variables.
Command line is:
valgrind ./debug/CSAssistServer

Any help would be welcome, alas the project is too large to send you as a
sample. I'm just about to see if I can generate the error with a test file.
<Valgrind works fine on other executables, there is clearly something about
this particular one, which is a very large server>

Note that this is often caused by mis-installation of valgrind.
Correct installation procedure is:
   ./configure --prefix=/install/dir
   make install
And then use /install/dir/bin/valgrind
Moving the installation directory elsewhere after 'make install'
will cause the above error.  Hand-editing the paths in the shell
scripts is also likely to cause problems.

Note: see also the FAQ.txt in the source distribution.
It contains workarounds to several common problems.

If that doesn't help, please report this bug to: js...@ac...

In the bug report, send all the above text, the valgrind
version, and what Linux distro you are using.  Thanks.
