Chris - thank you for the attachment - using it succeeded and perl 5.12 has also been successfully built. Gary - no edits, no. However, using Chris's attachment as 'my.patch' and the previous copy and paste from the inline code of ports/148648 as 'my.patch.old' for the diff run, below, you'll see that the two are obviously different.

It is somehow related to the Perl_debug_log which is the first
argument of PerlIO_printf. But I can not figure out why, too many
layers of #defines and calls within calls.
If I insert a line which references Perl_debug_log before the
problematic line, it will dump core on that line, gdb output:
Program received signal SIGSEGV, Segmentation fault.
0x006f2de0 in Perl_PerlIO_stderr (my_perl=0x0) at perlio.c:4981
4981if (!PL_perlio) {
I cannot inspect PL_perlio because it is another macro, from perlapi.h:
#define PL_perlio (*Perl_Iperlio_ptr(aTHX))
aTHX is defined in perl.h to be my_perl, which seems to be a null
pointer:
(gdb) p my_perl
$1 = (PerlInterpreter *) 0x0
So, the miniperl process dies because it cannot de-reference this
NULL pointer. I have no clue where it should be initialized.

The problem seems to go away when threads are disabled.
The problematic line 311 in util.c expands to quite a horrible mess
(found this out by doing make util.i):
(void)( { if ((PL_curinterp)) { PerlInterpreter* my_perl __attribute__((unused)) = ((PerlInterpreter
*)pthread_getspecific(PL_thr_key)); if (((my_perl-Idebug) 0x0080)) {(my_perl-Idebug)=~0x0080;

bytes\n,(UV)(ptr),(long)(my_perl-Ian)++,(long)count,(long)total_size); (my_perl-Idebug)|=0x0080;} } } );
The problem is that my_perl here is NULL pointer. PL_thr_key which
is given to pthread_getspecific() to get my_perl is zero.
(gdb) p my_perl
$1 = (PerlInterpreter *) 0x0
(gdb) p PL_thr_key
$2 = 0
(gdb)
