This test has failed for a while, but I can't find a bug report on it, so I'm
adding one here.

The test execute/va-arg-25.c with the -Os option compiles, but fails with a 
runtime abort with gcc 3.4.0, gcc 3.4.1, and the trunk.

With gcc 3.3.4, the test causes an ICE, with the message

internal compiler error: in ix86_function_arg_boundary, at config/i386/i386.c:2444

gcc 3.2.3 fails to compile the test because the vector support
needed is not present.

To repeat:

gcc -Os <dir>/gcc/testsuite/gcc.c-torture/execute/va-arg-25.c
a.out

I guess this isn't a regression, as I can't find a version that works.

I'm guessing "rtl-optimization" because only -Os fails; don't trust that guess.

------- Additional Comments From pinskia at gcc dot gnu dot org  2004-07-04 00:33 -------
Confirmed, the reason why it fails on i686 at -Os only is because of this code:
  /* Validate -mpreferred-stack-boundary= value, or provide default.
     The default of 128 bits is for Pentium III's SSE __m128, but we
     don't want additional code to keep the stack aligned when
     optimizing for code size.  */
  ix86_preferred_stack_boundary = (optimize_size
                                   ? TARGET_64BIT ? 128 : 32
                                   : 128);

So the problem is has to do with alignment problems on the stack and I know I have seen this bug 
before too.

Yes I commented in PR 15617 about the same exact problem and in fact I said var_arg25.c when I had 
meant va-arg-25.c.

*** This bug has been marked as a duplicate of 15617 ***

Not a duplicate of PR 15617, since PR 15617 is still not fixed...

Subject: Re:  va-arg-25.c -Os regression fails on i686

You say this is fixed, but I still get the abort from last night's build
of both 3.4 branch and trunk.  Was it fixed in the last 12 hours?

According to Andrew this was fixed on mainline by
http://gcc.gnu.org/ml/gcc-cvs/2004-07/msg00525.html

I get clean test results from tonight's build.
