undefined reference to `aligned_alloc'

Dear semargl-ng developer:
When compiling semargl-ng on our cluster, i got the error:
core/interp.c: In function ‘gsl_interp_continuous_axis’:
core/interp.c:88:19: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
double *y64 = (double *)aligned_alloc(ALIGNETOCACHE, sizeof(double) * size);

The "aligned_alloc" is only available in the glibc since glibc 2.16. Our current version of glibc is 2.12 and for security reason we cannot upgrade our system glibc, or install one in the user's /home directory.
Is there a way to replace those aligned_alloc with more general "malloc", if possible? Please help. I really appreciate if you could provide me a version/example using malloc.
Best,

@chenyuetian You are free to replace aligned_alloc with malloc.
