Hello!

As reported in [1], guile segfaults on 32-bit big-endian targets with:

I assume the crash has got something to do how values are packed and unpacked
into the SCM object type. I have not been able to find the problem yet myself,
unfortunately which is why I am reporting this issue here.

For anyone willing to debug this, access to a fast POWER machine running a
big-endian Debian unstable can be obtained through the GCC compile farm [3].

Thanks,
Adrian

Hi,

I created this debian PR earlier today:

I see this in scm.h:

/* The 0?: constructions makes sure that the code is never executed, and
   that there is no performance hit.  However, the alternative is
   compiled, and does generate a warning when used with the wrong
   pointer type.  We use a volatile pointer type to avoid warnings from
   clang.

   The Tru64 and ia64-hp-hpux11.23 compilers fail on `case (0?0=0:x)'
   statements, so for them type-checking is disabled.  */

Also just before, there is:
/* But as external interface, we define SCM, which may, according to the
   desired level of type checking, be defined in several ways.  */
#if (SCM_DEBUG_TYPING_STRICTNESS == 2)
  typedef union SCM { struct { scm_t_bits n; } n; } SCM;
# define SCM_UNPACK(x) ((x).n.n)
# define SCM_PACK(x) ((SCM) { { (scm_t_bits) (x) } })
#elif (SCM_DEBUG_TYPING_STRICTNESS == 1)
/* This is the default, which provides an intermediate level of compile
   time type checking while still resulting in very efficient code.  */
  typedef struct scm_unused_struct { char scm_unused_field; } *SCM;

The fault on hppa appears to be at strictness 1.

Dave

Guess, I should have copied the whole bit:

The last option is:
#else
/* This should be used as a fall back solution for machines on which
   casting to a pointer may lead to loss of bit information, e. g. in
   the three least significant bits.  */
  typedef scm_t_bits SCM;
# define SCM_UNPACK(x) (x)
# define SCM_PACK(x) ((SCM) (x))
#endif

I think strictness 1 may be problematic on hppa.

I did a build of the current debian package on hppa with type strictness =

I updated debian PR with additional analysis:

To be more specific, this is the type of sp:

(gdb) ptype sp
type = union scm_vm_stack_element {
    uintptr_t as_uint;
    uint32_t *as_vcode;
    uint8_t *as_mcode;

    double as_f64;
    uint64_t as_u64;
    int64_t as_s64;
    void *as_ptr;
    scm_t_bits as_bits;
} *
(gdb) p/x &((union scm_vm_stack_element *)$r26)[0].as_scm
$11 = 0xf34147f0

(gdb) p/x ((union scm_vm_stack_element *)$r26)[1].as_scm
$13 = 0x90020d
(gdb) p/x ((union scm_vm_stack_element *)$r26)[0].as_scm
$14 = 0x1
(gdb) x/8x 0xf34147f0
0xf34147f0:     0x00000001      0x00002c56      0x0090020d      0x0000097c

There are endian aspects to consider in accessing the scm_vm_stack_element struct.

I came to the same conclusion when I tried to bisect the git repo
between 3.0.2 and 3.0.3 on my powerpc machine. By reverting that commit
I was able to build 44ad8fbde55df452ac1c88427662403e7af5b9bb (3.0.2-70,
6 commit later) but wasn't able to build 3.0.3. I started the build
without any precompiled bootstrap .go files.

>=20

I spent some more time bisecting guile so I could create a diff against
3.0.5 and then spent another two weeks or so bootstrapping Guix from my
custom bootstrap binaries out to mesa.

I've attached the patch that's likely to go into Guix to add powerpc
support. Other than the mysterious failing test I've changed the
GUILE_OPTIMIZATIONS in bootstrap/Makefile.in to '-O1
-Oresolve-primitives -Ocps' on powerpc and it seems to be working fine.

Since this issue affects all 32-bit big-endian targets (hppa, m68k, ppc),
we should consider extending your patch to consider all these targets,
shouldn't we?

OK, I'll try a modified version of your patch on Debian and see if it helps.

I can confirm that adding "-Oresolve-primitives -Ocps" to GUILE_OPTIMIZATIONS
in bootstrap/Makefile.am fixes the problem for me on 32-bit PowerPC on Debian.

I will have to figure out how to add "-Oresolve-primitives -Ocps" on 32-bit
big-endian conditionally so that it is not passed for other architectures.
