[Bug c/38001] regression in 4.3: alignment checks wrongly optimized away (runtime failure)

[tg at mirbsd dot org]

------- Comment #4 from tg at mirbsd dot org  2008-11-03 15:55 -------
The aligned attribute is for data, not for the stack.
The gcc texinfo page says that gcc does not re-align
the stack once misaligned (it could do that though,
or you could do that yourself). But optimising away
the checks is something we’re used to from gcc4…
