Bernd Edlinger <bernd.edlinger at hotmail dot de> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |bernd.edlinger at hotmail dot de --- Comment #7 from Bernd Edlinger <bernd.edlinger at hotmail dot de> --- Joseph, gcc assumes that malloc, calloc, realloc, strdup, strndup and anything with the __attribute__((__malloc__)) returns a pointer that is aligned to MALLOC_ABI_ALIGNMENT bits. If not defined by the target, default.h sets it to BITS_PER_WORD config/i386 does not define MALLOC_ABI_ALIGNMENT. And BITS_PER_WORD is still 64 on x86_64 or 32 on i386.
