LINUX safe malloc ?

[MoranTza]

In Solaris I am using "-lmtmalloc", is there something similar in
LINUX.

BTW to make my concurrent malloc work I had to "setenv MALLOC_CHECK_
1"

Thanks,
Moran Tzafrir.

As of my knowledge, recent glibc on Linux uses ptmalloc2 which is
already optimized for multi-threaded process. You may want to
investigate other memory allocators like:
* hoard: http://www.hoard.org/
* nedmalloc: http://www.nedprod.com/programs/portable/nedmalloc/

HTH,

TCMalloc [1] might also be a solution.

There's also "libumem" (in OpenSolaris); it is concurrent and
has interesting features. It exists as of Solaris 10 and allows
for easy detecting leaks. Not sure whether it is easy to port
to Linux. (Finding leaks also requires the mdb debugger)
