The allocation size in chk_malloc(), leak_malloc(), and leak_memalign()
functions may be rounded up to a small value, leading to buffer overflows.
The code only runs in debugging mode.
This patch complements commit 6f04a0f4 (CVE-2009-0607).

This change is intended to eliminate need to replace libc.so with libc_debug.so in order to enablememory allocation debugging.
This is also the first step towards implementing extended memoryallocation debugging using emulator's capabilities in monitoring memory access.
