sorry, unfortunately the symptom only.
on {ia64,arm,m68k}-linux 3.3.4 fails to build a working miniperl, the one built
segfaults on the first invocation.
on ia64-linux, 5.8.3 builds using 3.3.4, 5.8.4 builds using 3.4 and using the
3.3 hammer branch.
maybe not a gcc regression in a strict sense.
build logs:

We need some kind of preprocessed source, otherwise there is not much we can do
about this.

I've just reproduced this on arm-netbsdelf using gcc-3.3.3. I've managed to
track it down to a miscompilation of pp_hot.c, and the key flag seems to be
-fcse-skip-blocks (-O2 -fno-cse-skip-blocks is OK, -O2 is not).

It's hard to be completely sure what's wrong here, but something *very*
suspcision appears near original source line 2669.
The good code (on ARM) contains:
.L1706:
.LBB453:
ldr r3, [r6, #4]
.LBE453:
.LBB454:
add r3, r3, #2
str r3, [r6, #4]
.LBE454:
mov r0, r5
mov r1, r6
bl Perl_save_freesv
but the bad code has
.L1705:
.LBB457:
ldr r3, [r6, #4]
add r3, r3, #1
str r3, [r6, #4]
.LBE457:
mov r0, r5
mov r1, r6
bl Perl_save_freesv
b .L1665
Note that in the second case r3 is only incremented by 1 not 2. This seems to
have come from the following pre-processed sequence:
cx->cx_u.cx_blk.blk_u.blku_sub.cv = cv; cx->cx_u.cx_blk.blk_u.blku_sub.o
lddepth = ((XPVCV*)(cv)->sv_any)->xcv_depth; cx->cx_u.cx_blk.blk_u.blku_sub.hasa
rgs = hasargs; if (!((XPVCV*)(cv)->sv_any)->xcv_depth) { (void)({ SV *_sv = (SV*
)(cv); if (_sv) (++(_sv)->sv_refcnt); _sv; }); (void)({ SV *_sv = (SV*)(cv); if
(_sv) (++(_sv)->sv_refcnt); _sv; }); Perl_save_freesv(my_perl, (SV*)(cv)); } cx-
>cx_u.cx_blk.blk_u.blku_sub.lval = (my_perl->Top)->op_private & (128|4);;
Note the double increment of sv->sv_refcnt.
