A fast freepascal memory manager using TCMalloc.
To build, first run build-tcmalloc.sh with root permissions (it'll have to install TCMalloc on your system).
Then, in every project where you want to use TCMalloc as the allocator, make sure the unit fpc_tcmalloc is the first unit included in your program. That way, no other units can allocate memory before this unit initializes.
This should work on every UNIX-like system. For windows, you'll have to build TCMalloc/gperftools yourself. For more information, see their README_windows.txt file.
Both the TCMalloc code included in the gperftools subrepository and my additions are licensed under the BSD-3-Clause license. See the COPYING file of gperftools and the LICENSE file.
