No. memtest86 tests viability of the RAM in your system. It's purpose
is to try and detect hardware problems with your systems memory.
What Johan wants is a package to do things like bounds checking of
dynamically allocated arrays and uninitialized memory read/write
checking, on code that he develops himself, or compiles himself
anyway.
I don't think any of the free ones come close to the functionality of
purify, but it's been a couple of years since I checked into it so the
situation may have changed. Johan, try one of these:
% apt-cache search malloc|grep -i debug
ccmalloc - A memory profiler/debugger
debauch - A malloc debugger
electric-fence - A malloc(3) debugger
fda - C malloc debug library
gccchecker - Memory access debugger for C language development
njamd - Not Just Another Malloc Debugger
dmalloc - Debuging memory allocation library
from a system running Debian "testing".
Also, if a commercial solution isn't totally out of the question you
can look into Insure++ (http://www.parasoft.com). I've run it on my
Debian "testing" system with moderate success.
