I'm trying to run Matlab 7.3 on a RedHat Linux EE4, x86_64 machine.  My aim is to check my MEX functions, which are dynamic objects that Matlab loads on the fly.
Valgrind seems to choke on an unrecognized instruction, and tries to kill Matlab.  Although Matlab catches the signal and recovers, I don't think it's in a trustworthy state anymore.  Below is the output, generated by inserting the following command into Matlab's wrapper script:

   /home/stevem/pkg/amd64/stow/valgrind-3.2.3/bin/valgrind  \
      /home/stevem/debug/matlabvg/bin/glnxa64/MATLAB -nodisplay -nojvm -r exit

jaws: ~/debug/matlabvg/bin % ./matlab
running the hacked wrapper script...

==28754== valgrind: Unrecognised instruction at address 0x11AC8807.
==28754== Your program just tried to execute an instruction that Valgrind
==28754== did not recognise.  There are two possible reasons for this.
==28754== 1. Your program has a bug and erroneously jumped to a non-code
==28754==    location.  If you are running Memcheck and you just saw a
==28754==    warning about a bad jump, it's probably your program's fault.
==28754== 2. The instruction is legitimate but Valgrind doesn't handle it,
==28754==    i.e. it's Valgrind's fault.  If you think this is the case or
==28754==    you are not sure, please let us know and we'll try to fix it.
==28754== Either way, Valgrind will now raise a SIGILL signal which will
==28754== probably kill your program.
