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. Adrian -- .''`.

>=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.

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;
SCM as_scm;
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
$12 = 0xf34147f8
(gdb) x/x 0xf34147f0
0xf34147f0: 0x00000001
(gdb) x/x 0xf34147f8
0xf34147f8: 0x0090020d
(gdb) p/x ((union scm_vm_stack_element *)$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
0xf3414800: 0x00000007 0x00000c83 0x0000097d 0x000d007f
There are endian aspects to consider in accessing the scm_vm_stack_element struct.

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.

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_PACK(x) ((SCM) { { (scm_t_bits) (x) } })

/* This is the default, which provides an intermediate level of compile

The fault on hppa appears to be at strictness 1.

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
