Re: Alignment of malloc returned pointer

Hi,

In glibc, I understand that the alignment of the pointer returned by
malloc is aligned to at least __alignof__ (long double). For our
target, we want to have a different version of malloc that return the
pointer with less alignment compared to __alignof__ (long double) and
leave the existing malloc version as is.

This isn't allowed, assuming your target has an ABI with _Alignof(max_align_t) == _Alignof(long double).

For details, take a look at:
7.22.3 Memory management functions
6.2.8 Alignment of objects
