Issue #17356 has been updated by shyouhei (Shyouhei Urabe).


Sadly that has portability issues.  It is not always possible to pass a pointer returned from aligned_alloc to realloc.  You are lucky to have an environment with that capability.  But we can”Ēt always replace malloc with aligned_alloc.

Feature #17356: Alignment of memory allocated through Fiddle struct's malloc
https://bugs.ruby-lang.org/issues/17356#change-88863

* Author: AndreaRibuoli (Andrea Ribuoli)
* Status: Open
* Priority: Normal
----------------------------------------
I am testing a low-level patch for **Ruby 3** that inside *gc.c* replaces:

  `TRY_WITH_GC(size, mem = malloc(size));`

with:

  `TRY_WITH_GC(size, mem = aligned_alloc(16,size));`

This should allow me to control that Fiddle returns pointers quad-words aligned.

Is it possible to introduce a configure parameter to control this kind of setting?

Refer to [issue opened on Fiddle](https://github.com/ruby/fiddle/issues/53).

Kind regards,

   Andrea Ribuoli
