[PATCH] Resolve bug when using unusual MALLOC_ALIGNMENT
by Eyal Itkin 30 Mar '20

30 Mar '20

Safe-Linking alignment checks should be done on the user's buffer and not the mchunkptr. The new check adds support for cases in which: MALLOC_ALIGNMENT != 2*(sizeof(size_t)) The default case for both 32 bits and 64 bits was already supported, and this patch adds support for the described irregular case.
