libc 2.3.5 and heap corruption checking?
My system did everything I thought to ask of it under libc 2.3.2.
However, Matlab (for me the Killer App) breaks under libc 2.3.5.
Almost certainly this is a bug in Matlab, but breaking large, popular
commercial apps could be considered bad policy. Especially now that
2.3.5 is moving into Testing, there really needs to be some
workaround. Or is this just something funky about _my_ system?
Latest unstable, kernel.org kernel 2.6.13 (but same problem with 2.6.9
and others since installing libc 2.3.5).
I'm running Matlab Version 7.0.4.352 (R14) Service Pack 2. It seems
to work fine until I take an outer product, at which point it says
something like
*** glibc detected *** malloc(): memory corruption: 0x083ba0e8 ***
zsh: abort (core dumped) matlab -nosplash -nojvm
Just for completeness I've run it with MALLOC_CHECK_ unset and then
set to [0, 3], although I suspect it's already obvious to y'all what
the problem is. Since the output is rather long I've attached it as a
separate file. I'm happy to make available corefiles if they would be
useful.
I guess this is related in some sense to #304604 / #322746 / #323849?
I installed an old libc6_2.3.2.ds1-22_i386.deb that I had lying around
on my Testing system, and of course this broke most executables, but
it fixed Matlab.
Is it possible to keep libc 2.3.2 in a special directory just for
Matlab (I used to keep libc5 around for Matlab R5)? I extracted it to
/usr/local/foo and set LD_PRELOAD, but I get a bunch of
ERROR: ld.so: object '/usr/local/foo/lib' from LD_PRELOAD cannot be preloaded: ignored.
...and Matlab still chokes as before. I assume my preload-fu is weak
and there's a correct way of doing this?
Many thanks for reading!

Please follow these steps in reporting this problem to The MathWorks so
that we have the best chance of correcting it:
1. Send this crash report to segv@mathworks.com for automated analysis.
2. Also, if the problem is reproducible, send the crash report to
support@mathworks.com along with:
- A specific list of steps that will reproduce the problem
- Any M, MEX, MDL or other files required to reproduce the problem
- Any error messages displayed to the command window
A technical support engineer will contact you with further information.
Thank you for your assistance. Please save your workspace and restart
MATLAB before continuing your work.
[ note: here Matlab hung, so I had to go to another window and kill it
remotely ]
