Custom malloc/mmap for x86_64
Sat Apr 28 22:03:00 GMT 2012
so you just want to override the malloc implementation ? glibc is specifically
designed to allow that at runtime today.
if you create a shared library that exports these functions:
malloc calloc realloc memalign free
you can use it with LD_PRELOAD and both glibc and your own code will use the
custom allocator functions on the fly. then to switch back to the stock glibc
ones, unset LD_PRELOAD.
