i386: Increase MALLOC_ALIGNMENT to 16 [BZ #21120]
GCC 7 changed the definition of max_align_t on i386: https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=9b5c49ef97e63cc63f1ffa13baf771368105ebe2 As a result, glibc malloc no longer returns memory blocks which are as aligned as max_align_t requires. This causes malloc/tst-malloc-thread-fail to fail with an error like this one: error: allocation function 0, size 144 not aligned to 16 This patch moves the MALLOC_ALIGNMENT definition to <malloc-alignment.h> and increases the malloc alignment to 16 for i386. [BZ #21120] * malloc/malloc-internal.h (MALLOC_ALIGNMENT): Moved to ... * sysdeps/generic/malloc-alignment.h: Here. New file. * sysdeps/i386/malloc-alignment.h: Likewise. * sysdeps/generic/malloc-machine.h: Include <malloc-alignment.h>.
