--- Comment #6 from Hussam Al-Tayeb <me at hussam dot eu.org> ---
Do I need a debug build of glibc for this?
I am getting

(gdb) run
Starting program: /home/hussam/cache/workspace/c/a.out 

Breakpoint 1, main () at memalign.c:5
5           void *p = 0;
(gdb) c
Continuing.

Breakpoint 2, main () at memalign.c:6
6           int ret = posix_memalign(&p, sizeof(void*), 0);
(gdb) p __malloc_initialize_hook
No symbol "__malloc_initialize_hook" in current context.
(gdb)
