Not performance, but the brokenness to test might actually be related to
the use of GCC's *built-in* malloc().
Perhaps, I don't know which GCC-4.3.2 bug this refers to.
If this is the case, it obviously should not be changed to malloc() and
the right thing to do is checking for the existence of __builtin_malloc().
#ifdef __clang__
# if __has_builtin(malloc)
# define __builtin_malloc malloc
# else
# define __builtin_malloc malloc
# endif
#endif
;-)
clang's built-in malloc() is just malloc(), not __builtin_malloc(),
available with -fbuiltin (default).
(__has_builtin(malloc) evaluates to false with -fno-builtin.)
(I'm not saying I like this.)
