--- Comment #1 from Kostya Serebryany <kcc at gcc dot gnu.org> ---
Interesting. This is a relatively new c11 feature.
On older Linux distros this does not compile nor link:
aligned_alloc.c: In function ‘main’:
aligned_alloc.c:5:3: warning: implicit declaration of function ‘aligned_alloc’
[-Wimplicit-function-declaration]
void * p = aligned_alloc(128, 1024);
...
/tmp/ccJJcsqx.o: In function `main':
aligned_alloc.c:(.text+0x13): undefined reference to `aligned_alloc'
On Ubuntu 14.04 it behaves as you describe and indeed we need to add an
interceptor. The tricky part is to add a test that will work on older distros
